近10年来京杭大运河扬州市区段水质变化趋势研究

Research on the Change of Water Quality at the Section of Yangzhou City of the Beijing-Hangzhou Grand Canal in Recent Ten Years

根据1996-2007年京杭大运河扬州市区段水质监测数据,按照《地表水环境质量标准》GB3838-2002中Ⅲ类水质标准,选用内梅罗水污染指数法,运用方差分析,对京杭大运河扬州市区段水质现状进行分析。从内梅罗综合污染指数可知,在1998-2001年间京杭大运河扬州市区段呈重污染状态,其余年份以呈污染状态为主。针对扬州市经济发展和产业结构及布局对河流环境的影响,提出了加强建设生态经济型城市的建议。

According to the basic analytical methods of Environmental Quality Standards for Surface Water in China （GB3838 -2002）,the 1996 -2007 monitoring data were used to evaluate water quality condition of Yangzhou reach of Beijing - Hangzhou grand Canal based on the Nemerow index and analysis of variance com- ponent. When it came to the Nemerow index, it was severely polluted during 1998 to 2001, while in other years it was lightly polluted. In view of the effect of the economic development and industrial structure in Yangzhou city on the river environment, the suggestions on constructing an eco - economic city are proposed in this article.
