摘　　要：为推进国产卫星数据的应用,本文以CBERS-02B卫星的CCD数据和HR数据为数据源,以重庆市涪陵区为实验区,将DEM、NDVI数据作为补充,采用分层分类的方法,对实验区土地利用/土地覆盖现状信息进行提取,分析CBERS-02B数据的特点及在应用中存在的问题。研究结果表明,CBERS-02B数据可满足复杂地区土地利用宏观监测的需要。The CBERS-02B is China＇ s first civilian high-resolution remote sensing satellite, which starts the imagery distribution from 2007. It has been widely applied in many fields, such as the land using, urban planning, disaster prevention and mitigation. In order to promote the application of domestic satellite data, this paper chose the CBERS-02B muhi-spectral and high-resolution imagery as data source and Fuling district in Chongqing as experimental area, and studied both extraction method of land use/land coverage information and characteristics of different surface objects. This paper also studied the applied problems of CBERS-02B data. In the study, hierarchical method, using DEM and NDVI data as supplements was applied in the classification. The result indicated that the CBERS-02B data could basically meet the requirement of land use macro-monitoring in complex region.
