摘　　要：对上海市入河排污口的水质进行分析,指标包括化学需氧量、悬浮物、氨氮和总磷,可知上海市入河排污口水质情况总体较好.同时,采用单因子指数法和主成分分析法分别对水质数据进行评价,得出上海市入河排污口基本能够达标排放,且在2018年-2019年的水质数据总体较为平稳,无明显变化,但处于枯水期时的水质稍劣于丰水期.最后建议采用2种评价方法相结合的方式,为上海市入河排污口管理工作提供数据依据和新思路.Water quality of pollution discharge outlets of rivers in Shanghai has been analyzed,the indexes including chemical oxygen demand,suspended solids,ammonia nitrogen and total phosphorus.It can be seen that water quality of pollution discharge outlets of rivers in Shanghai is generally well.At the same time,the single factor index method and principal component analysis method are used to evaluate water quality data respectively,and it is concluded that pollution discharge outlets of rivers in Shanghai can basically reach the discharge standard,and water quality data in 2018-2019 is generally stable without obvious change,but water quality in the dry season is slightly worse than that in the wet season.Finally,it is suggested that two evaluation methods should be combined to provide data basis and new ideas for the management of pollution discharge outlets of rivers in Shanghai.
