摘　　要：南水北调中线干渠来水水质与沿线受水区水源水质存在一定程度差异,形成生活、生产和生态的用水风险。根据南水北调中线干渠和沿线受水区水源地的水质监测数据,分析各水源地水质特征,比较主客水的水质指标差异。综合基于单因子评价方法的饮用水水源地水质评价、基于拉森指数的水体腐蚀能力评价、基于综合营养水平指数的水体营养程度评价等,探索建立科学性、系统性、实用性的水质差异评价体系,为制定科学的供水计划、措施、管理提供参考依据。There is a certain difference between the water quality of the middle route of the South-to-North Water Transfer Project and the water receiving area,which forms the risk of water use in life,production and ecology.Based on the water quality monitoring data of the middle route of the Southto-North Water Transfer Project and the water receiving area,the w ater quality characteristics of each water source area were analyzed,furthermore,the differences of the water quality indexes between water supply source area and water receiving area were also compared.In addition,the single factor evaluation method was used to assess water quality of water source area,the Larsen-index-based method was applied to analyse stability evaluation of water pipe-line,and the comprehensive nutrient level index method was used to evaluate water nutrition level.On the basis of these results,the differences of water quality in different water source areas can be evaluated.The research can provide a reasonable and effective basis for establishing a scientific,systematic and practical water quality difference evaluation system,and developing scientific water supply plan of the middle route of the South-to-North Water Transfer Project.
