摘　　要：淀浦河是黄浦江的重要支流,七莘路断面位于淀浦河中下游,其水质状况对周边环境及下游的黄浦江有重要影响。因此本文对七莘路断面的枯丰水期的水质特征进行分析,并探究不同污染物之间的相关性。结果表明:枯水期的主要污染因子为总氮、氨氮和总磷,总氮、总磷和溶解氧是丰水期的主要污染因子,枯丰水期间的总氮的超标率都分别达到了91.91%和100%。对污染物间的相关性分析显示出,总氮与氨氮、总磷呈现显著的正相关性,与pH值和溶解氧呈负相关性,与高锰酸盐指数间的相关性不大。Dianpu River is an important tributary of the Huangpu River.The Qishen Road section is located in the middle and lower reaches of the Dianpu River,and its water quality has an important impact on the surrounding environment and the downstream Huangpu River.Therefore,this paper analyzes the water quality characteristics of Qishen Road section in dry and wet seasons,and explores the correlation between different pollutants.The results showed that the main pollution factors in dry seasons were total nitrogen,ammonia nitrogen and total phosphorus.Total nitrogen,total phosphorus and dissolved oxygen were the main pollution factors in wet seasons.The over standard rate of total nitrogen in dry and wet seasons reached 91.91%and 100%respectively.The correlation analysis between pollutants showed that total nitrogen had a significant positive correlation with ammonia nitrogen and total phosphorus,a negative correlation with pH and dissolved oxygen,and little correlation with permanganate index.
