摘要
本文以"3S"技术为技术背景,以中巴地球资源卫星CBERS-02为遥感数据源,对贵州省黔南布依族自治州喀斯特石漠化进行遥感解译,基于最佳指数波段选择法推算出喀斯特地区石漠化分类的最佳波段组合.实验表明,中巴资源卫星影像不但可以替代具有相似空间分辨率和光谱波段设计的国外遥感影像TM和SPOT,作为喀斯特石漠化监测的重要手段和主要的信息源,而且能够较好地满足大比例尺石漠化成图的需要,为制定喀斯特石漠化综合防治规划提供依据.
With ＂3S＂ （GIS, GPS＆RS） techniques as the background and remote sensing digital image manage technique as the support and CBERS -01/02 as the data, the paper explores the best image manage methods and classification methods for dynamic monitoring of land use change in the Karst area, and finds an new method by modeling which can solve the problem of water and shadow, building and dry land, paddy field in karst area. It is proved that national image TM and SPOT can be substituted by CBERS, and CBERS can be applied to dynamic monitoring of land use change in karst area. CBERS becomes an important means and primary information in monitoring of environment.
