为科学指导调水工作，全面掌握南水北调东线江苏段地表水资源质量状况及其水质变化趋势，应用季节性Kendall 检验法，选取溶解氧、高锰酸盐指数、五日生化需氧量、氨氮、石油类、挥发酚6项污染指标，对2001-2012年南水北调东线（江苏段）14个控断面水质变化进行分析评价，从污染物类型、河流级别和行政区域三个方面对水质变化结果进行分析比较。结果表明：2001-2012年间，①按污染物种类分，南水北调东线江苏段研究区域内6项水质评价指标均呈变好趋势；②按河流级别分，支流水质呈变好趋势，输水干线水质除石油类指标趋势变差外，其它均呈变好趋势；③按行政单位分，扬州段BOD5、淮安段石油类、宿迁段溶解氧和CODMn水质变差外，其它段均呈变好趋势。

In order to provide guidance for water diversion work ,it is necessasy to master comprehensively the water quality status and water quality change trend of south -to-north water diversion project area of Jiangsu province .The paper applied the seasonal Kendall method and chose six pollution indices such as DO、CODMn、BOD5、NH3-N、petroleum and volatile phenol from 2001 to 2012 in water route in South-to-north water diversion project area of Jiangsu province to analyze water quality variation tendency of water quality .The results showed that from 2001 to 2012:①According to type of pollutants , the six water qual-ity indices changed for better .②According to grade of rivers , the water quality of tributary is good , the water quality of trunk stream except oil index become worse , the other show better trend .③According to administrative unit , the water quality is poor because of BOD 5 in Yangzhou section , Petroleum in Huaian section , DO and CODMn in Suqian section, the other segment shows better trend .
