摘　　要：采用模糊综合评价法对京杭运河扬州段水质进行评价,研究结果表明:京杭运河扬州段上游水质明显好于下游,上游7个断面全部为Ⅰ和Ⅱ类水质;而下游6个断面全部为Ⅳ和Ⅴ类水质。影响运河水质的主要污染因子为粪大肠菌群、COD、TP和NH3-N,沿岸工业废水和生活污水的排放仍然是影响水质的主要原因。在今后的治理工作中,只有加大对下游运河市区段水质的治理力度,才能保证南水北调东线工程输水干线水质达到Ⅲ类水质的预期目标。The water quality of Jinghang Canal in Yangzhou was evaluated by fuzzy comprehensive assessment method. The results show that the water quality in the upstream reaches is better than that in the downstream reaches. The seven sections in the upstream reaches belong to Ⅰ and Ⅱ type water quality, and the six sections in the downstream reaches belong to Ⅳ and Ⅴ type water quality. The main pollution factors influencing the water quality of the canal are fecal coliform, chemical oxygen demand, total phosphorus and ammonia nitrogen. This is mainly due to the discharge of industrial and domestic wastewater along the canal. Only increasing the control effect on the water quality of Jinghang Canal in the downstream cities can ensure that the water quality of east route project of South to North water transfer reaches the Ⅲ type target.
