| 摘 要： | 应用2007年8月29日Landsat-5 TM多光谱影像,在现场实测支持下反演石头口门水库水质参数.在对室内水质实验获得的20个样点的7个变量进行集群分析(CA)与主成分分析(PCA)的基础上,建立起水质参数多元估算算法,最终将算法应用于影像生成石头口门水库整个区域水质参数空间分布专题图.

| Abstract: | Water quality parameters were retrieved for the Reservoir Shitoukoumen using Landsat-5TM data acquired on August 29,2007 supported by concurrent in-situ measurements.On the basis of cluster analysis(CA) and principle component analysis(PCA) of twenty water samples with seven variables,multiple regression algorithms were established and subsequently used to produce water quality spatial distribution maps over the entire geographic area. |
