摘要：
The karst collapse is one of the six major geological disasters in China, the karst region is also the main geological disasters, to the integration of subsidence data management and evaluation is particularly important. In this paper, Lai bin, Jili of Guangxi province is taken as an example, combining RS and GIS technology for thematic information extraction and data management, extracted from remote sensing image subsided land use types; Use of GIS software ArcGIS for platform, combining with subsidence history text, drawings, and on-the-spot field to get the data, established the perfect combination of spatial database, graphic data of subsidence geological environment evaluation and spatial analysis provides a scientific and effective management; The last, The use of GIS space analysis function to completed accurate sensitivity assessment collapse rapid.
