ABSTRACT
Zoning degree of landslide danger involves analysis of the environment conditions, the triggering factors and the situation of the landslide, which together determine the danger risk. Several steps are concerned with the zoning: choosing evaluation indexes; establishing models; classifying hazard degrees; testing the result; and quantifying the degrees. Three primary problems are also discussed: the choice of evaluation index, the establishment of weight, and the classification of hazard degree. Model Zoning sampling Gridding-sampling statistics method is employed to carry out hazard degree zoning, establishing sampling areas of different scales Si according to the range of zoning. Evaluation index of landslide hazard degree can be determined by the integrity and liability of environmental data of the research area. Method of classification of hazard degree should be further explored for the sake of facilitating application and reliability.
