摘　　要：本研究选取松花江流域32个研究断面,收集2003年-2019年监测数据,通过相关性分析、主成分分析和因子分析研究流域环境质量状况,解析松花江流域水体主要污染影响因子。结果表明①NH+4-N和TN是平水期最主要的水质影响参数,NH+4-N、TN、BOD5和COD是丰水期主要的水质影响参数,NH+4-N、TN、NO-3-N和TP是枯水期最主要的水质影响参数。②T和DO是水体污染物浓度的影响因素之一,生活源是枯水期水体主要污染来源。平水期和丰水期工业污染影响增大。The quality of water environment in SHR has an important influence on the natural environment and economic and social development within the basin.In this study,32 research sections of SHR were selected to collect monitoring data from 2003 to 2019.Through correlation analysis,principal component analysis and factor analysis,the environmental quality and the main pollution influencing factors of the SHR were analyzed.The results can provide technical support for the control of water pollution in the SHR.The results show that.(1)NH+4-N and TN are the most important water quality influencing parameters in flat flow season,NH+4-N,TN,BOD5 and COD are the most important water quality influencing parameters in high flow season,and NH+4-N,TN,NO-3-N and TP are the most important water quality influencing parameters in low flow season.(2)T and DO are highly correlated with other indexes and are one of the influencing factors of water pollutant concentration.Living sources are the main sources of water pollution in low flow season.The influence of industrial pollution increased during high flow and flat flow season.In recent years,with the implementation of relevant pollution control measures,the water quality of SHR has been continuously improved,but nitrogen pollution is still the most important pollution impact factor in SHR.
