摘　　要：研究了梁子湖水环境主要污染因子。分别采用综合污染指数法和卡尔森综合营养指数法对梁子湖入湖口、中心梁子岛、东梁子湖湖心、出湖口等监测点的水质状况和营养状态进行评价。结果表明,梁子湖的出湖口水质状况最好,入湖口最差;全湖处于中营养状态;总磷、总氮、CODCr、CODMn、BOD5为梁子湖主要污染因子;梁子湖主要污染物的来源主要包括外源污染物的流入、区域内面源污染等。We studied the main pollution factors of water environment in the Liangzi Lake.Moreover,we evaluated the water quality and nutritional status of lake entrance,center of Liangzi Island,East Liangzi Lake center,lake exit by the comprehensive pollution index method and Carlson comprehensive nutrition index method,respectively.The results show that the water quality of lake exit is the best and that of lake entrance is the worst.The whole lake is in a state of medium nutrition.TP,TN,CODCr,CODMn,and BOD5 are the main pollution factors.The sources of five main pollutants in the Liangzi Lake include the inflow of exogenous pollutants and the pollution of non-point sources in the region,etc.
