摘　　要：根据2000-2001年汉江丹江口水库水质监测资料，对水质整体状况和营养盐变化特征进行研究，结果表明，丹江口水库水质总体状况良好，库周气温和水温变化不大，pH值中性偏碱，白河站、丹江口站、凉水河站和清泉沟站的水质能够达到或优于地表水Ⅱ类水质要求;襄樊站污染较严重，其中主要为唐白河口和小清河口，两断面溶解氧较低，电导率、SS、CODMn、NH3-N、NO3-N、NO2-N、T—P等均出现峰值，说明工业、企业和城镇生活污水的点源和非点源排放较严重。According to the monitor data from 2000 to 2001, the water quality of Danjiangkou reservoir was analyzed and assessed. The results showed that the water quality of Danjiangkou reservoir was better in all, the temperature of air and water did not change very much, the value of pH is above 7, and the stations of Baihe, Danjiangkou, Liangshuihe and Qingquangou reached the level Ⅱ. Only the pollution in Xiangfan station was worse, especially DO is lower in the two transects of Xiaoqinghekou and Tangbaihekou, but other indexes of water quality were higher, which indicated that the point and non-- point pollution were serious.
