大鹏湾近岸海域叶绿素a的时空分布特征

The spatial and temporal distribution characteristics of Chlorophyll-a in the coastal waters of Mirs bay

  • 摘要: 根据2015年度大鹏湾近岸海域5个海洋环境浮标的在线监测数据,分析大鹏湾海域海水中叶绿素a(Chl a)的时空分布特征及其与主要水质参数的相关关系。结果表明大鹏湾Chl a含量在春、夏、秋季较高,而冬季较低,实测最大值为82.23 μg/L;受水动力环境及陆源排放影响,终年沙头角附近海域的Chl a含量明显高于其他区域。Pearson相关分析结果表明,大鹏湾海域Chl a含量与水温呈现正相关关系,但与盐度不存在显著意义的相关关系。总体来看,Chl a含量的时空分布受陆地径流、外源输入和养殖环境状况等的共同影响。

     

    Abstract: Based on the on-line monitoring data of 5 ocean environmental buoys in Mirs bay in the 2015, this paper analyzes the temperal and spatial characteristics of chlorophyll-a in the coastal waters of Mirs bay and its corrections of the main water quality parameters. The results show that the maximum value of chlorophyll-a in winter is 82.23 μg/L, which is the lowest one compared with the other three seasons. Affected by the hydrodynamic environment and land-based emissions, it was perennially higher in the Sha Tau Kok Sea zones than the other zones of Mirs bay. The results of Pearson correlation analysis showed that the chlorophyll-a concentration was significantly proportional to water temperature, but when comparing the chlorophyll-a concentration with salinity, there was no obvious correlation between them. Overall, the spatial and temporal distribution of chlorophyll-a concentration is influenced by the land runoff, the external waste loads, the aquaculture environment and so on.
