摘　　要：河流水质评价和污染源分析对河流污染治理和有效管理具有重要的意义。基于2019年6月(枯水期)和8月(丰水期)大汶河干流和主要支流21个监测断面16项水质指标的检测数据,综合运用单因子污染指数法、内梅罗污染指数法和因子分析法对大汶河流域水质状况和污染来源进行了评价与分析。结果表明:大汶河流域水体整体水质较差,以Ⅴ类水为主,21个断面枯水期Ⅴ类水质断面占比为66.7%,丰水期Ⅴ类水质断面占比为81%;枯水期大汶河水质明显优于丰水期,且从大汶河上游至下游其水质污染程度逐渐加重;大汶河流域水体中主要污染物为TN、NH+4-N、Hg和Se等,属有机污染和重金属污染类型,污染物主要来源于流域耕地面源性污染和冶金、化工、纺织等工业企业工业废水的排放。该研究结果可为大汶河流域水体污染治理提供依据。River water quality evaluation and pollution source analysis are of great significance to river pollution control and effective management.Based on the detection data of 16 water quality indicators at 21 monitoring sections along the main stream and main tributaries of the Dawen River in June(low flow period)and August(high flow period)in 2019,this paper applies Single-factor pollution index method,Nemero pollution index method and factor analysis to evaluating and analyzing river water quality pollution sources.The results are as follows:the water quality of the Dawen River Basin is poor,with ClassⅤ(poor water quality)being the main water quality category.The proportion of the 21 sections with ClassⅤwater quality is 66.7%during low flow period,and 81%during high flow period.The water quality in the low flow period is obviously better than that in the high flow period,and the pollution degree gradually increases from upstream to downstream.The main pollutants in the Dawen River are TN,NH+4-N,Hg,and Se,which belong to organic pollution and heavy metal pollution types.The pollutants mainly come from the non-point source pollution of cultivated land and the discharge of industrial enterprises such as metallurgy,chemical industry and textile industry.This study can provide basis for water pollution control in the Dawen River Basin.
