| 摘 要： | 上海经济的快速发展，将加剧滨岸带的高强度开发，致使滨岸带的环境结构发生变化，通过对上海滨岸带水体的深入调查、样品采集、分析测试和对比研究，对上海滨岸带水体的自净作用进行了总体评价，除排污口外，污染物含量一般低于一类海水标准，表明了水体具有较强的自净能力，环境容量较大；并指出水体中重金属、氮、磷和难降解有机物含量明显增多，水体环境质量有逐渐下降的趋势。

| Abstract: | The fast development of economy of Shanghai will strengthen the exploitation of coastal water zone and cause the change in environmental structure. The pouring of sewage water in great quantity and the pollutants contained in the water of Changjiang has affected the self purification in costal water. By the thorough investigation, sampling, analyzing and contrasting study towards the coastal water beside Shanghai, based on the analysis of water self purification, the paper has evaluated water self purification. Beside outlet of sewage water, the content of pollutants in seawater is generally lower than the first type seawater standard, which indicates larger self purification competence and environmental potential in coastal water. However, the content of heavy metal, organic matter, nitrogen and phosphorus in seawater has markedly increased, and water environmental quality has the decreasing trend. |
