摘　　要：为更准确掌握四川二滩库区水污染情况,科学评估水库水质,根据2016-2019年度水质逐月环境监测数据资料,对二滩水库三个断面的水质污染状况及营养化状态进行了分析,结果表明库区综合污染指数下降,综合营养指数显示二滩水库的营养化程度由中营养化向贫营养化转变,出库断面水质略优于入库断面。In order to more accurately grasp the water pollution in the Ertan reservoir area of Sichuan,the water quality of the reservoir should be evaluated scientifically.?Based on the monthly environmental monitoring data of water quality from 2016 to 2019,the water pollution status and eutrophication status of three sections of Ertan Reservoir were analyzed.the results showed that the comprehensive pollution index decreased.The comprehensive nutrition index showed that the eutrophication degree of Ertan reservoir changed from mesotrophication to poor eutrophication,and the water quality of the outlet section was slightly better than that of the entry section.
