基于GIS和RS的重庆市滑坡遥感解译

Remote sensing interpretation of landslide in Chongqing based on GIS and RS technologies

地处三峡库区腹心的重庆市由于其复杂的自然地理环境及不断增加的人类工程活动,使该市域内滑坡灾害较为频繁。在分析重庆市滑坡特征的基础上,采用高精度遥感影像及基础地形数据,在地理信息系统和遥感等技术支持下综合解译重庆市滑坡灾害,探讨了针对重庆市滑坡灾害的解译和识别方法,为地方政府滑坡灾害防治提供决策支持。

Located in the hinterland of the Three Gorges reservoir area,Chongqing City is characterized by the complex natural and geographical environment and increasing human activities,leading to more frequent landslide disasters of the city area.Based on analysis of characteristics,this paper interprets the landslide disasters in Chongqing comprehensively on use of geographic information systems and remote sensing technologies with high-precision remote sensing images and topographic data,discusses the interpretation and recognition methods to Chongqing landslide disasters,and provide decision support for local governments to prevent landslide.
