南水北调东线（江苏段）水质变化趋势分析
Analysis of change tendency of water quality in east line of south-to-north water diversion project of Jiangsu section
摘要
Abstract
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 .关键词
