以杭州湾海域水环境调查的相关数据为依据，研究杭州湾海域水污染演变及污染源情况。杭州湾海域常年以劣四类海水为主，水质状况极差，部分指标仍有恶化趋势。其主要超标污染物为无机氮和活性磷酸盐，化学需氧量浓度波动较大，但不是杭州湾水污染的主要威胁。从海域污染源来看，从富春江电站上游区域汇入的污染物占比最多；其次是杭州湾沿岸支流河道汇入的污染物；再次是从排海污水处理厂纳入的污染物。

Based on the related data from the survey on Hangzhou Bay water environment,the paper analyzed the process and the degree of the water deterioration and pollution in Hangzhou Bay.All year round, the water in Hangzhou bay contains mainly of four categories of poor sea water,some indexes of which are turn-ing worse.The main non-compliance pollutants are Inorganic nitrogen and Active phosphate in Hangzhou Bay. Although the concentration of chemical oxygen has fluctuations,it is not the main threat for the water pollution. With regard to the pollution source of the sea,the upstream region of Fuchun Rive power plant produced the largest proportion of pollutants;second,the pollutant coming from the tributaries along the coast of the Hang-zhou Bay;last,the pollutants from the wastewater treatment plant.
