摘要：
There are highly efficient, timely, accurate and simple features of the landslide hazard assessment with the platform of GIS. With the spatial analysis of GIS, it can be obtained the data which is needed when assess the landslide hazard with the application of comentropy; Then standardized and normalized the results of the analysis, for obtaining the weights of all evaluation indicators and all sub-factors of each indicator; Finally, establish the corresponding layers with the weight of all sub-factors of each indicator, with the spatial overlay functions of GIS, comprehensively analyzed the layers of weight of all the evaluation indicators with the application of weighted sum, and obtained the results of landslide hazard assessment of study area. It was verified the correctness and feasibility of the evaluation application by the example of Cangxi county.
