Application of Remote Sensing and GIS in Environment Background of Water Quality Analysis--A Case Study in Jilong River,Taiwan
遥感与GIS在河流水质环境背景分析中的应用——以台湾基隆河为例

In order to indicate the effect of the environmental background of a drainage basin and human activity on the river's water quality,TM and SPOT images,thematic maps,statistic data and in field measured data were used to analyze the relationship of Jilong River water quality with its environmental background and urban pollution.According to the relations between the reflectivity of water and its suspended sediment concentration,band 1 and 2 of SPOT image were used to classify the concentration of suspended sediment into 4 grades on base of the in field measured data.The environmental background of Jilong River basin were acquired by environmental remote sensing mapping with TM and SPOT images and thematic information based on GIS.Compareing the water quality with the environmental background of the basin and the location of limber holes,it can be concluded that its environmental background and urban sewage affect the water quality of Jilong River.
