摘要: 以京杭大运河无锡段水质监测数据和2003年7月SPOT-5正射影像为数据源,分析土地利用面积比例与过境水质之间的响应关系。结果表明:以监测断面为中心缓冲区距离的空间变化与水质监测指标之间有明显的响应关系。运河水质污染主要受离河岸较近的土地利用结构的影响。耕地上产生的农业污水,商业和工业中的废水以及大面积裸地上居民生活垃圾和建筑垃圾产生的污水是导致京杭大运河无锡段水质恶化的重要原因。

Abstract: Taking the six sections’ water quality monitoring data of Beijing-Hangzhou Grand Canal in Wuxi and SPOT-5 orthophoto images in July 2003 as the data source, this paper analyses the response relationship between land-use area proportion and the transit water quality. The result shows that the spatial change of the buffer distance which takes the monitoring section as center responds to the five water quality monitoring indexes. The canal water quality pollution is mainly affected by land use structure which is close to the river. So the agricultural effluent, commercial and industrial wastewater and effluent from large area of bare land which is made by living rubbish and construction refuse is an important reason to make the Beijing-Hangzhou Grand Canal water quality worse.
