山东近岸海域夏季pH分布特征及影响因素分析

Distributions and influencing factors of pH in Shandong coastal area in summer

  • 摘要: 本文基于山东近岸海域2020年7月-8月表层海水pH、温度、盐度、叶绿素a、溶解氧等数据,研究了夏季山东近岸海域表层海水pH的分布特征及受控因素。结果表明:2020年夏季,山东近岸海域表层海水pH范围为7.76~8.62,平均值为8.12±0.11;莱州湾pH最高,渤海湾pH最低,在不同区域环境条件下pH的受控因素存在差异;夏季,渤海湾表层pH受径流引起的水团混合以及微生物对有机质的矿化分解的影响显著;由陆源营养盐输入引起的浮游植物光合作用的增强,是控制夏季莱州湾表层海水pH的主要因素;烟威北部海域pH受黄海冷水团影响明显,由温度、盐度控制的碳酸盐解离平衡过程对pH也产生影响;南黄海近岸海域pH除受黄海冷水团的影响外,部分区域还受浮游植物光合作用等因素的影响。

     

    Abstract: Based on the data of pH, temperature, salinity, chlorophyll a and dissolved oxygen of surface seawater in Shandong coastal area from July to August in 2020, the distribution characteristics and influencing factors of pH in Shandong coastal area were studied. The results showed that the pH of surface seawater in Shandong coastal area in summer was 7.76~8.62, with an average of 8.12 ± 0.11. The pH of Laizhou Bay was the highest and that of Bohai Bay was the lowest. In summer, the surface pH of Bohai Bay was significantly affected by the mixing of water masses caused by runoff and the mineralization and decomposition of organic matter by microorganisms. The enhancement of photosynthesis caused by the input of terrestrial nutrients was the main factor controlling the pH in Laizhou Bay. The pH of the northern coastal area of Yantai and Weihai was significantly affected by the cold water mass of the Yellow Sea, and the equilibrium process of carbonate dissociation controlled by temperature and salinity also had an impact on pH. The pH of the South Yellow Sea was not only affected by the cold water mass of the Yellow Sea, but also affected by photosynthesis.
