摘　　要： 本文以遥感和地理信息系统相结合的方法对我国西南边陲的瑞丽江、大盈江流域的湿地进行了动态监测研究。通过分析和处理遥感图像建立了湿地的遥感解译标志;采用计算机自动分类、相关分析法和GIS矢量化的方法提取了湿地信息;以差异主成份法、多波段主成份分析法、分类比较法、光谱特征变异法等,检测湿地的动态变化范围、位置、大小等,分析了该地区的湿地动态变化趋势及原因。 Integrating applications of the GIS and RS technology,this paper had conducted the dynamic monitoring survey of the wetland of the basin of Ruilijiang river and Dayingjiang river in the southwest of china.Different kinds of wetlands extracting signs had been established by analyzing and processing the remote sensing images.The wetland information was extracted by the RS and GIS method,such as the computer automatic classification,correlation analysis and vectoring.Then the size position and the scope of dynamic changes were detected by components of difference,components of multiple bands,classification comparison and variation of spectra features.Finally,the paper analyses the trends and causes of the wetlands dynamic changes in this region.
