Abstract:
The transparent exopolymer particles(TEP), a kind of transparent colloidal particulate matter, consists of extracellular polysaccharides. TEP is of great significance to the carbon cycle of marine ecosystems. In this study, two marine diatoms, Ditylume brightwelii and Chaetoceros affinis, were studied. The TEP concentration, the relationship between TEP and Chlorophyll a (Chl a) and the C∶N ratio of TEP were studied at different growth phases. The results showed that TEP was produced by both species during the whole growth phases, and TEP concentration was different in different growth phase. The maximum TEP concentration of D. brightwelii and C. affinis was produced in the exponential phase and the decline phase, respectively. The maximum TEP concentration per cell volume and per Chl a of C. affinis was 184.91±14.03 fg Xeq/μm3 and 38.06±4.96 μg Xeq./μg Chl a, and were 16 and 5 times higher than the values obtained from the D. brightwelii. The analysis of the relationship between Chl a and TEP in two diatoms showed that the function relationship between TEP=α (Chl a) β was presented in the exponential phase (D. brightwelii: R2=0.98; C. affinis: R2=0.80). The TEP C∶N ratio of both diatoms was higher than the Redfield ratio (C∶N=106∶16). It indicates that the generation of TEP was difference between species, and the growth phase significantly affects the efficiency of TEP production. The high carbon concentration of TEP show that TEP production contributes significantly to the ocean carbon cycle.

Abstract:
Export fluxes of sinking particulate organic carbon (POC) are important for the function of biological carbon pump. Vertical transportation of POC into the ocean interior can be affected by particle-attached bacteria (PAB) via the change of their abundance and activities, which may eventually affect the carbon sequestration into the ocean. In order to better understand the characteristics of PAB in the turbid nearshore waters along the Pearl River Estuary (PRE), we applied and modified an existing analytical procedure to effectively detach PAB from sinking particles for more direct and accurate estimation of PAB. The coupling relationship between environmental factors and the abundance of PAB were further analyzed and discussed. our results suggested that PAB from the fraction 2~20 μm particles was the dominant component of PAB in all stations. Moreover, there was a spatial change of PAB along the PRE with the highest abundance at Xiangzhou port (4.21×109 cells/L), following by Zhongda port (1.13×109 cells/L) and Wanshan island (0.27×109 cells/L). We also found that suspended organic particles might have supported PAB growth at Xiangzhou port where there was high PAB but low chlorophyll a. In addition, the growth of PAB might also subject to influences by varying concentrations and species compositions of inorganic nutrients in coastal waters. These results may be important for further understanding of PAB associated biogeochemical processes in coastal ecosystem.

Abstract:
A sediment core was collected in the Jiaozhou bay in 2011. The concentrations of eight heavy metals (mercury (Hg), arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn)) in the sediment core from 0 m to 1 m were measured. These raw data were then utilized to calculate the enrichment factors (enrichment factors, EFs, represents the enrichment status of elements) of these metals. The results showed that both concentrations and EFs of these heavy metals presented a peak or had the highest value in the subsurface layer (at around 20 cm) of the sediment core. The age of sediment at such depth was estimated to be around 20 years using the reported sediment settlement rate. This indicates that the contamination of heavy metals in Jiaozhou bay sediment may be significantly affected by the high-intensity anthropogenic discharge of heavy metals into the Jiaozhou bay in the late 1980s and 1990s. Pearson correlation and multiple regression analyses were further performed to investigate the primary controlling factors for heavy metals in Jiaozhou bay sediment. The results suggest that the inter-annual variations of the eight common heavy metals may be controlled by different environmental factors in Jiaozhou bay sediment. In addition, the potential ecological risk index was calculated to evaluate the potential risks of these heavy metals in Jiaozhou Bay sediment and their historical variation trends. Mercury generally had a moderate risk in the Jiaozhou bay, and its risk has been increasing in recent years. This finding suggests that Hg should be put in the priority metal to be controlled in the Jiaozhou bay.

Abstract:
The total 21 surface sediment samples were collected in the sea area around Liandao island, which is located in Haizhou bay, Jiangsu province, China. The heavy metals (Cd, Cr, Cu, Pb and Hg) contents and the metal-like arsenic (As) content were determined. The spatial distribution maps of heavy metals and metal-like As were obtained by using Kriging interpolation method. The pollution degree and risk grade of heavy metals and metal-like As were assessed by ground accumulation index and potential ecological risk index respectively. The results were indicated that the average content of heavy metal Cu was higher than the Class 1 standard according to the Marine Sediment Quality (GB 18668-2002). The variation coefficients of heavy metal Cu and Pb were 114.66% and 108.44% respectively. Therefore, they had strong spatial dispersion. The pollution degree of heavy metals and metal-like As ranked from large to small: Cd>Pb>Cu>As>Hg>Cr based on the analysis results of ground accumulation method, in which heavy metal Cd, Cu and Pb were the moderate pollution, As and Hg were mild pollution, and Cr was non-pollution. The overall potential ecological risk level in the sea area of Liandao island reached the medium level. There existed the high ecological risk level of heavy metals and metal-like As in the southern part of Liandao island. Further, the ecological risk of surface sediments was mainly caused by heavy metal Cd.

Abstract:
Dissolved gaseous mercury (DGM), reactive Hg (RHg), total Hg (THg) and dissolved Hg (DHg) concentrations were analyzed in the seawater of the East China Sea (ECS) during a cruise in June 2018. The distribution patterns of DGM and RHg and their controlling factors in the East China Sea (ECS) were investigated. The concentrations of DGM and RHg in the seawater were determined to be 151.3±75.9 pg/L and 0.8±0.7 ng/L, respectively. The ratios of DGM/THg, DGM/RHg and RHg/THg were calculated to be (4.5±2.5)%, (26.7±15.0)% and(21.6±14.8)%, respectively. DGM and RHg concentrations in the ECS water were significantly higher than that in most open oceans, but lower than or comparable to that reported in most coastal seas. Both DGM and RHg in the seawater presented a complicated spatial distribution pattern, with high concentration areas located in both nearshore shallow seawater, and offshore shallow and deep seawater. These results indicate that both species of Hg may be controlled by both the terrestrial input and in situ production/removal processes. As for the vertical distribution, the concentrations of DGM and RHg in the bottom seawater were observed to be the lowest, while comparable concentrations were observed at all the other sampling layers. Although highest THg concentration was observed in the bottom seawater of the ECS, DHg concentrations in the bottom seawater were slightly lower than those at the other layers. This may be a reasonable explanation of the lower RHg and DGM concentrations in the bottom water. Spearman’ correlation and multiple regression analyses suggest that RHg and dissolved oxygen (DO) concentrations may be the major controlling factors for DGM in the seawater, while RHg in the seawater may be controlled by DO.

Abstract:
The study interpreted seven temporal satellite remote sensing images of Zhoushan Petrochemical Base project area, Combined the collection of relevant information and the field survey of landing on the island, extracted and analyzed the changes of coastline and vegetation distribution in different periods of Zhoushan petrochemical base construction through remote sensing (RS) and geographic information system (GIS). The results show that natural shoreline of island group reduced by 21.335 km in Zhoushan Petrochemical Base Project which accounts for 75.4% of the original natural coastline. Vegetation of island group reduced by 3.537 km2 which accounts for 74.0% of the vegetation area of the original island group in the past three years. The change of island group can be divided into four stages: the development of main island Dayushan, the process of connecting Dayushan Island and Xiaoyushan Island, the island group enclosed as a whole and enclosure period of island group expansion. In the first three stages, the natural shoreline of island group decreased rapidly, the artificial shoreline increased rapidly. In the fourth stage, the natural shoreline decreased slowly, and the artificial shoreline rushed up and fell back quickly. The vegetation of the island group decreased rapidly in the first two stages and slowly in the latter two stages. The above characteristics are mainly related to the process of the project construction. It is suggested that the island management department should do a good job in ecological protection and restoration in the development of the island group because of the serious influence to the original ecological environment of the island group created by the project development.

Abstract:
Coastal line is not only the space carrier of marine economic development in coastal areas, but also an important platform to protect the marine environment and maintain the ecological balance of coastal zone. Generally speaking, it can be divided into natural shoreline and artificial shoreline. Since the 1990s, with the rapid economic and social development of China's coastal areas, the intensity of offshore sea area and coastline development has been increasing. By 2018, the proportion of artificial coastline in China has exceeded 75%, and that of individual provinces and cities has exceeded 90%. Overload development and utilization of the coastline has brought about environmental problems, and also caused difficulties in the protection and management of the coastline. It is suggested that work should be carried out from the perspectives of establishing coastline management system, establishing responsibility supervision mechanism of natural coastline retention rate, implementing coastline rehabilitation and implementing coastline supervision and management and so on, so as to promote the protection and utilization of coastline resources in China in the new era.

[Abstract](353) [FullText HTML](312) [PDF 893KB](5)
Abstract:
In order to study the distribution of polycyclic aromatic hydrocarbons (PAHs) in the sediment-seawater system, 16 kinds priority control PAHs in the sediments and seawater from 9 sampling points at the Xiangshan port were analyzed in January 2017. The source analysis and diffusion equilibrium were conducted by isomerism ratio method and fugacity approach. The concentrations of PAHs in the sediments ranged from 17.51×10-9~84.41×10-9, mainly high ring PAHs, and the pollution level was minor polluted. The PAHs in the sediments primarily came from high temperature combustion sources. The ranges of PAHs in the surface seawater, intermediate seawater and bottom seawater were 41.78~105.72 ng/L, 41.51~106.34 ng/L and 9.18~145.17 ng/L, respectively, which low ring PAHs were the most abundant compounds. The sources of PAHs in seawater originated mainly from oil leakage and oil combustion. The fugacity fraction was calculated to judge the diffusion behavior of PAHs. Nap, Ace and Flo were released from sediments to seawater. Acy, Phe, Ant and Pyr were close to the dynamic equilibrium in sediments and seawater. Flu, BaA, Chr and BbF were mainly diffused from seawater to sediment.

Abstract:
The sea surface temperature has been retrieved from Landsat 8 TIRS 10, which shows that the water temperature nearby the discharge area of Nanpu power plant are increased in summer and winter compared with that in the reference area. The scope of water temperature rise is larger and the degree is smaller in summer, while the scope of water temperature rise is smaller and the degree is larger in winter. The thermal discharge pollution from the power plant goes northwest to Waiwu island at rising tide, and moves to southeast at ebb tide. Due to the coal wharf and diversion dike, thermal discharge has little effect on intake. The retrieving results based on satellite images are consistent with the numerical simulation results before project construction.

Abstract:
Archaeal community plays an extremely important role in marine biosphere and affects the cycling of carbon, nitrogen, sulfur, iron, and other elements in marine ecosystems. There are a large number of archaea in marine sediments. The investigation on their distribution and diversity lays the basis of understanding their ecological functions. In this study, the sediments of Jiaojiang Chemical Industry Park of Zhejiang Province were sampled, and metagenomic analysis based on the Illumina Miseq PE300 high throughput sequencing platform was applied to investigate the Archaea community. A total of 52 genera, 37 families, and 11 phyla of Archaea were detected from the sediments. Thaumarchaeota was the most predominant phylum, accounting for 49% of the total abundance, followed by Crenarchaeota, Euryarchaeota, and Woesearchaeota. Nitrosopumilus was the most abundant group at genus level, accounting for 48% of the total abundance. Obvious spatial heterogeneity was found in marine sedimental environment in the study area, which might have an impact on the archaeal community structure. Cadmium, lead, arsenic, chromium, mercury and other heavy metals were significantly correlated with certain archaeal phyla.

Abstract:
In this study, 11 organophosphorus esters (OPEs) in the surface water from mariculture farms, estuaries and the nearshore of the Qinzhou bay were analyzed. The total concentration of 11 OPEs averaged 126 ng/L and ranged from 32.9 to 227 ng/L the mean, which was at the lower level among the similar regions worldwide. The predominant contaminants were TCEP, TCPP and TBEP. The level of individual OPEs in the Qinzhou bay was mainly affected by their own aqueous solubilities and octanol-water partition coefficients (KOW) as well as their productions and consumptions. In general, the concentrations of OPEs were higher in the aquaculture ponds than in the nearby estuaries and nearshore area. The OPEs accumulated in the ponds might be mainly from the sources of culture water: rivers and coastal water. Chlorinated OPEs were more persistent than non-chlorinated OPEs in the culture ponds. So far, the concentrations of OPEs in the study area have no significant ecological impact on the surrounding environment, but its potential threat to human cannot be ignored because of their possible bioaccumulation in seafood.

Abstract:
The sources of microplastics in coastal areas are complex. The fragmentation of large plastics through physical, chemical and biological processes is one of the main sources of microplastics in the beaches. This study investigated the compositions, abundances, shapes, colors and components of plastic debris and the microplastics of different sizes in 7 beaches in Sanggou bay of the Yellow Sea. We also studied the relationships between the fragmentation of plastic debris and microplastics by qualitative and quantitative analysis, which can be used to identify the sources of the microplastics. The results showed that polystyrene foam accounted for 85%, 97% and 82% of the samples in the size range of 5 mm ~ 2.5 cm, 1 ~ 5 mm and <1 mm respectively. In plastic debris >2.5 cm, the types of the plastic debris related to mariculture accounted for 76%. The total abundances of plastic debris and microplastics increased by 2 ~ 4 orders of magnitude with the decrease of sizes and the abundances of microplastics and plastic debris in 1 ~ 5 mm and 5 mm ~ 2.5 cm were significantly correlated. By comparing the morphology and components characteristics of different sizes of plastic debris and microplastics, the sources of microplastics were identified as fragmentations from polystyrene foam, polyethylene float, yellow sponge, fiber fishing ropes and polypropylene film ropes. The results indicate that mariculture is one of the important sources of plastic debris and microplastics in beaches of Sangou bay. In the future, it is necessary to further explore the identification methods of sources and find new evidences to identify the sources of microplastics.

[Abstract](598) [FullText HTML](439) [PDF 762KB](7)
Abstract:
Full polarization interferometric radiometer, which can image from interferometric synthetic aperture and get full polarization information, is the new type of microwave radiometer that can measure various physical information of ocean with high resolution and low consumption. By introducing the development of full polarization and synthetic aperture respectively, we expound on the necessity and principle of full polarization and synthetic aperture to aquire ocean information. Taking the advantages and disadvantages of WindSat and MIRAS as an example, we have discussed the advantages of multi-functional microwave radiometer and multi-load microwave sensors satellite to observe ocean. Moreover, to develop our satellite observation of ocean salinity, the necessity and the difficulity of collaborations of full polarization interferometric radiometer are pointed out for the application of multiple microwave remote sensing.

Abstract:
Timely pretreatment and proper storage of nutrient samples are the pre-conditions to ensure the reliability of data. In this study, we examine the differences between frozen storage and preservation with mercury chloride at room temperature for dissolved silicate in the Yellow River water sample that is characterized of high turbidity. We found out that there was no significant difference between the two storage methods. We compared in-situ filtration (freezing stored in 9 mL vacuum polyethylene terephthalate tube) and delayed filtration (freezing stored in 125 mL high density polyethylene bottle) for the nutrients, and discussed the effects of delayed filtration time on nutrients data quality. Nitrite, nitrate and phosphate were not affected by prolonged filtration time, while ammonium was significantly impacted by a decrease of 11%~46%, possibly due to suspended particulate matter adsorption and/or phytoplankton assimilation. As for silicate, storage container and its volume may play a major role in silicate storage while the prolongation of filtration time is much less important.

Abstract:
Four cruises were carried out in April, August, October 2011 and January 2012 in the Sanggou bay.The concentrations of dissolved iron (DFe) were measured by catalytic kinetic spectrophotometry.The average concentrations of DFe were 3.8 ±0.7 nmml/L, 3.3 ±1.8 nmol/L, 2.6 ±1.0 nmol/L, and 1.8 ±0.6 nmol/L respectively, which showed significant seasonal difference among the four cruises (t-test, p < 0.05, n=19).The distributions of DFe were similar during the study periods, with the high concentrations occupying the estuaries and coastal area, and decreased towards the offshore.A preliminary box model was established to estimate the budgets of DFe for the Sanggou Bay, which demonstrated that the major sources for DFe in the Sanggou bay included the inputs from riverine and groundwater discharge, atmospheric deposition.The main sinks included the output into Yellow Sea and the absorption or accumulation by biological activities.The residence time of DFe in the Sanggou bay is much shorter than the open ocean, which might be related to the special hydrological condition and the absorption concerning aquaculture activities.

Abstract:
With the increase of sewerage discharge, PAHs pollution has become more serious.3, 4-benzo (a) pyrene, 9, 10-dimethylanthracene, 3-methylphenanthrene are carcinogenic PAHs in ocean.Sea cucumber (Apostichopus japonicus) is a widely cultured economic species in the coast of China.Therefore, it is particularly important to study the bioaccumulation of PAHs by sea cucumber.The semi-static two-compartment kinetic model was used to simulate the bioaccumulation experiment of 3, 4-benzo (a) pyrene, 9, 10-dimethylanthracene, 3-methylphenanthrene by Apostichopus japonicus.The bioaccumulation kinetics parameters of 3, 4-benzo (a) pyrene, 9, 10-dimethylanthracene, 3-methylphenanthrene were achieved by nonlinear curve fitting.The results showed that sea cucumber has ability to accumulate 9, 10-dimethylanthracene, 3, 4-benzo (a) pyrene and 3-methylphenanthrene.The enrichment ability and rate of sea cucumber to the three polycyclic aromatic hydrocarbons increase with the increase of the concentration of the three polycyclic aromatic hydrocarbons in the seawater.The absorption processes of PAHs conform to two-compartment kinetic model under the conditions of 3, 4-benzo (a) pyrene 5 μg/L, 9, 10-dimethylanthracene 10 μg/L and 3-methylphenanthrene 100 μg/L concentrations.The BCF of the three PAHs absorbed by sea cucumber are in the order of 9, 10-dimethylanthracene 148.3>3, 4-benzo (a) pyrene 126.9 >3-methylphenanthrene 88.0 at the concentration of 5 μg/L.

Abstract:
In this paper, focusing on the suspended matter (in water), water (Pb in water) and sedimentary (Pb in sediment) phases of Pb in the Caofeidian offshore engineering marine, trend analysis and multivariate statistical correlation analysis method is proposed for analyzing the trend and correlation among the suspended matter, water and sedimentary phases of six years.The aim is to reveal the evolution law and enrichment characteristics of Pb under the influence of artificial disturbance factors.Trend analysis results show that with the increase and decrease of suspended matter, the water phase presents the basic same regularity, but the sedimentary phase is showing the opposite trend.Simple correlation analysis results show that the suspended matter was weak positive correlation with the water phase, suspended matter was a strong negative correlation with sedimentary phase, and a weak negative correlation existed between water and sedimentary phase.Compared with simple correlation, partial correlation results show that the correlation change of water and sedimentary phase is the biggest, that is to say, the water and sedimentary phase is greatly influenced by suspended matter.The correlation change of suspended matter and water phase is lower than the correlation change of water and sedimentary phase.The suspended matter and sedimentary phase is weakly influenced by water phase, owing to the small correlation change.The multi-phase change trend and correlation research of Pb has important practical significance to provide the guidance for nearshore environmental management and engineering construction.

Abstract:
In order to investigate the influence of human activities within the Yalu River catchment, in terms of the import of terrestrial inputs from the Yalu River, on the sedimentary environment of the estuary and continental shelf mud deposition area, two sediment cores, Q02 and Q04, were collected from the mud deposition area of the eastern Liaodong Peninsula.Subsequently, the content of 210Pb dating, grain size, total organic carbon (TOC), total organic nitrogen (TN), stable carbon isotope (δ13C) were analyzed; finally, the C/N ratio and δ13C value were used to analyze the contribution of different organic matter source.The results show that:(1) TOC and TN were gradually increased during the past 100 years.The C/N ratio ranged from 9 to 11, indicating that the organic carbon is characterized by terrestrial and marine mixing sources. (2) The organic carbon proportions originating from terrestrial and marine source indicated a decreasing and increasing trends, respectively, implying that the eastern and western of the study area suffered from different controlling factors.In the eastern area, the sedimentary environment is mainly affected by catchment environment change and land-sea interaction:reclamation, natural disasters and wars caused the vegetation cover reduced, and the reservoir construction decreased the input of terrestrial organic carbon.The sedimentary environmentof eastern area is mainly controlled by human activities and water eutrophication:"Closure" Policies result in the destruction of vegetation cover, and the ports construction, aquaculture lead tothe increase of nutrients in the water bodies, which cause deterioration of the marine environment.

Abstract:
Particulate nutrients have been proved to be the important components of nutrients in seawater.In this study, particulate nitrogen (PN) and particulate phosphorus (PP) were measured in four different seasons to investigate the seasonal distribution patterns and their potential ecological roles in Daya bay.The results showed that the concentrations of PN and PP ranged from 2.63 to 26.24 μmol/L (averaged 8.20 μmol/L) and 0.11 to 3.71 μmol/L (averaged 0.39 μmol/L), respectively.The main component of PN was particulate organic nitrogen (PON), accounting for 65.0%; while PP was made up by 63.4% particulate inorganic phosphate (PIP).Meanwhile, PN and PP accounted for 24.8% and 37.0% of total phosphorus (TP) and total nitrogen (TN), respectively.PN and PP showed a decreasing trend from the inner bay to the outer bay except in winter.Runoff input and phytoplankton were considered to be the main factors controlling the spatial distribution as well as contents of particulate nutrients.In addition, the average PIN/PIP value in Daya bay was 13.2±11.1, which was close to the Redfield ratio (16:1).However, average DIN/DIP ratio (49.1±39.7) was much higher than 16:1.These combined results suggested that particulate nutrients probably played an important role in buffering and regulating nutrient structure in Daya bay.

Abstract:
In order to understand the impact of human activities on the changes of wetland landscape types in the Yellow River Delta wetland and to identify the dominant human factors, this paper uses Landsat 1976, 1986, 1996, 2006, 2016 satellite data and uses landscape transfer matrix, and human activity intensity model to quantitatively monitor the wetland landscape types under the influence of human activities in the Yellow River Delta during the 40 years and assess the impact of human activities by partitioning in the study area.The results are as follows:(1) Three kinds of conversions that are greatly affected by human disturbance:natural wetlands to human-made wetlands and non-wetlands are the most, and non-wetlands to human-made wetlands are medium, and human-made wetlands to non-wetlands are the least. (2) The proportion of landscape types that have been affected by human disturbances in the study area has been increasing, and the impact rate of human activities has increased from 16.77% in the first 10 years to 52.93% in the last 10 years.Farmland farming was the main human activity factor affecting the change of landscape types from 1976 to 2006.Between 2006 and 2016, the distribution of changes in natural wetlands area affected by various human activities is relatively balanced, and the proportion of transfer to reservoirs ponds is 34%.Farmland reclamation was the main influence in 1976-2016. (3) The human activity intensity model is applicable to the calculation of human activity intensity in the Yellow River Delta wetland.Between 1976 and 2016, severe disturbances were mainly concentrated in coastal areas, undisturbed and interference weakening areas were mainly concentrated in nature reserves.The results are in good agreement with the actual field survey results.The results of the study can provide a useful reference for the relevant departments to protect, manage and rehabilitate wetlands in the Yellow River Delta.

Abstract:
The species and quantities of hazardous chemicals are increasing year by year with the rapid development of national economy in coastal area of China, and the leakage risk of hazardous chemicals is increasing, which pose the potential threat to marine ecological environment.This article focused on the Rizhao Lanshan port, which is the largest bulk hazardous chemicals distribution center, and took the paraxylene that the annual throughput account for approximate 41% of total amount of hazardous chemicals as the research object, then forecasted the marine environmental impact of the accident that paraxylene leaked into sea with the maximum credible quantity in three scenarios.The simulation prediction results showed that the high concentration range of paraxylene was mainly located in the port and near the port area when leakage accidents happened on shore (50 ton paraxylene leakage of operational accident in chemical terminal or 800 ton paraxylene leakage of chemical tank accident), and there was no impact on the three ecological protection zone.When 2, 000 ton paraxylene leakage happened on the channel due to transport ship accident, the leaked paraxylene under the SSE and in the ebb phase would begin to affect the three ecological protection zone located in northeast 4 hours later, and the maximum concentration was 5 mg/L, while all the leaked paraxylene would volatilize 8 hours later, so the impact duration time is very short.However, all the leaked paraxylene under other conditions would evaporate before affecting the three ecological protection zone.

Abstract:
Coral reefs are one of the most biologically diverse, valuable and fragile marine ecosystems on earth.In recent years, coral reefs around the world have been experienced bleaching resulting from anthropogenic activities, climate change and environmental pollution.Global warming and sea surface temperature anomaly induced coral bleaching events are the greatest threats to coral reefs.Coral reefs and associated tropical near-shore ecosystems have suffered massive, long-term decline in abundance, diversity, and habitat structure.Therefore, coral bleaching monitoring is of great importance to the management of marine ecosystem and the conservation of the biodiversity.This paper reviewed the monitoring methods of coral bleaching at home and abroad, which can be divided into three types, that is, in-situ observation, ecological monitoring and remote sensing monitoring methods.We introduced and commented briefly the principles, advantages and disadvantages of each method, and the development tendencies of the monitoring method in the near future were also given.Among the methods, the methodology based on remote sensed sea surface temperature has been the most widely used, but the accuracy of monitoring method needs to be improved for small scale coral bleaching.The monitoring of coral bleaching in the US and Australia started earlier and has been routinely operated in the world.In contrast, our country started relatively late and lagged behind in monitoring methods.

[Abstract](7) [FullText HTML](4) [PDF 3283KB](2)
Abstract:
According to ecosystem service functions, an evaluation index system is established for evaluating the effects of coastal zone ecological restoration, which includes 15 indexes of four aspects of services such as supply service, regulation service, cultural service and support service.The analytic hierarchy process (AHP) is adopted to determine the weights of each indexes and the concept of Commercial Bank interest rate is introduced to build up the evaluation model of ecological restoration effect.By using this index system and evaluation model, the values of the ecosystem service functions in the coastal zone of Tianjin in 1983, 2005, 2012 and 2016 are estimated.The results how that by taking 1983 as the base year, the total value of the ecosystem services in the coastal zone of Tianjin in 2005, 2012 and 2016 has fallen by 82.47%, 89.78% and 88.66%, respectively, tending to decline.However, the proportion of leisure and entertainment to the total value tends to increase, indicating that through the local ecological restoration this function is improved quickly and the cultural objectives of ecological restoration can be achieved basically.For the life support service function of the ecosystem, however, it is difficult to restore to the historical level.Generally speaking, the ecological restoration projects that have been carried out locally in the coastal zone of Tianjin in the past 30 years has not yet received a good effect on the restoration of ecosystem service functions in the whole coastal zone of Tianjin.It is difficult to make up the losses caused by the continuous degradation of the coastal zone through the ecological restoration in a short period.
