采用模糊数学法对扬州市内城河“十一五”期间的水质监测数据进行了综合评价。评价结果表明：扬州内城河水质较差，2005年-2010年内城河对Ⅴ类水质隶属度最大。总磷、氨氮和五日生化需氧量为主要污染因子。可见内城河水质较差的主要原因是有机类污染导致富营养化。整个“十一五”期间，内城河对Ⅴ类水质隶属度逐年减小，说明水质总体趋于好转。

The monitoring data of urban rivers in Yangzhouwas comprehensively evaluated using fuzzy mathematics during the 11th five-year plan.The results showed that the water quality was poor and more belonged toⅤgrade.Total phosphorus, ammo-nia nitrogen and biochemical oxygen demand were the main pollution factors .The main reason for the poor quality of urban river was organic pollution leads to eutrophication.The river ofⅤgrade was decreasing year by year and the water quality was improved during the 11thfive-year plan period.
