摘　　要：为了解南水北调中线工程水源地的水质状况,选取丹江口库区河南段水体为研究对象,通过研究环保部2006—2015年对丹江口库区河南段的水质状况调查数据,采用综合污染指数法对研究区域的水质情况进行定量分析。结果表明:按照综合污染指数法的水质分级标准,丹江口库区河南段水体的水质状况属尚清洁类,但仍存在一定的污染风险,水质有恶化的趋势;通过对南水北调中线工程水源地河南段污染源的分析,发现点源污染对水源地水环境的影响较为严重,面源污染的危害也不可忽视;南水北调中线工程水源地河南段的点源污染源分布较为广泛,但主要集中在丹江口水库北支控制单元。研究结果可为保护水源地的水质安全和控制污染源提供理论依据。In order to investigate the water quality of water source area in the middle route of South to North Water Transfer Project, we selected the water body in Henan in Danjiangkou Reservoir area as a research object, by analyzing the data of water quality in Henan in Danjiangkou Reservoir area from 2006 to 2015 from the Ministry of Environment Protection of China and using the synthetic pollution index evaluating method, we quantitatively analyzed the water quality of research area. The results show that the water quality in Henan in Danjiangkou Reservoir area is up to the clean level by the analysis results of synthetic pollution index evaluating method, but it still has a certain polluted risk, and the water quality has a deteriorative trend ; By analyzing the pollution fountain of water source area in Henan in the middle route of South to North Water Transfer Project, we find that the point pollution seriously affects the water environ- ment of water source area, and the harmfulness of non-point pollution is not ignored ; The point pollution of water source area in Henan in the middle route of South to North Water Transfer Project is more widespread, but it mainly concentrated at the control unit of north branch of Danjiangkou Reservoir. These research results can provide a theoretical guarantee for the safety of water quality and the con- trol of pollution fountain of water source area.
