| 摘 要： | 通过对历年调查与监测数据的整理,从污染物源强、渤海富营养化状况、赤潮发生的时空分布三个角度,分析了渤海近岸海域富营养化的"压力—状态—响应"耦合作用机制。根据文献及调查资料研究渤海营养要素的来源及通量,指出渤海污染物主要来自于陆源输入,并且以河流携带的营养盐输入为主。在对渤海近岸海域历年营养盐含量及富营养化水平分析的基础上,结合赤潮发生的时空变化特征,就富营养化对渤海赤潮的诱导作用与耦合关系进行初步讨论。

| Abstract: | According to the past years’ investigation data,"Pressure-Status-Response" eutrophication mechanism of Bohai Sea was established,by analyzing the pollution sources,eutrophication status and spatial-temporal character of algae blooming in Bohai Sea.Land-based and sea-based discharge,and atmospheric deposition of nutrient loads to Bohai Sea were compared,and the main source was recognized as riverine discharge of nutrients.Relationship between the nutrient loads from the main rivers and the eutrophication level of Bohai Sea was studied.The spatio-temporal distribution of algae bloom events in Bohai Sea was investigated in recent years.The inducing effects and coupling mechanism of eutrophication to algae bloom events were established. |
