摘　　要：基于天津市的多水源供水状况,选取浊度、高锰酸盐指数、总氮、总磷、硫酸根和氯离子等6个水质指标作为评价因子,采用物元可拓法对天津市南水北调中线来水和引滦入津工程来水这2个水源的水质进行了等级评价。评价结果显示:南水北调中线来水水质等级为Ⅰ类,引滦入津来水水质等级为Ⅲ类,南水北调中线来水水质优于引滦入津来水水质。该方法水质评价结果客观真实,可为相关部门的水质管理提供依据。Based on the multi-water source situation in Tianjin, taking turbidity, permanganate index, total nitrogen, total phosphorus, sulfate and chloride as the evaluation factors and using matter- element extension method, the water quality of the middle route of the South to North Water Diversion Project（SNWDP） and the Luanhe River to Tianjin Water Diversion Project（LRTWDP） were evaluated. The evaluation results showed that the water quality of the middle route of the SNWDP was grade I of the national standards and the water quality of the LRTWDP was grade III of the national standards. The water quality of the middle route of the SNWDP was better than that of the LRTWDP. The evaluation results were authentic and objective, which could provide reference for the relevant departments to manage water quality.
