摘　　要：通过选取2016-2022年衡阳市生活源废水中总磷排放量及湘江衡阳段归阳、熬州、城北水厂等6个较有代表性的地表水环境质量监测断面总磷年均浓度进行相关性分析,结果表明生活源总磷排放量与单个断面的总磷年均浓度相关性较差,与各断面浓度的均值呈现正相关,即随着生活源总磷排放量的增加,水环境中各断面总磷浓度的均值将对应上升。The total phosphorus(TP)discharge from urban life pollution sources in Hengyang and the annual average concentration of TP in six representative monitoring sites of surface water quality,including Guiyang,Aozhou and Chengbei waterworks in Hengyang section of Xiang River,were selected for association analysis.The results showed that the total phosphorus emission had a poor correlation with the annual average concentration of total phosphorus in a single cross-section,and had a positive correlation with the average concentration of each cross-section,the mean concentration of total phosphorus in the water environment will rise correspondingly.
