Open publisher page 22 citations

Abstract

With the development of hazard prevention and reduction in China, it is imperative to assess regional landslide hazards. Information value model, which is based on the Information Theory, is the valid method for analyzing the risk of regional geo-hazards. The risk assessment supported by GIS is one of the most important directions in geo-hazard study. Based on the author's studies, a risk analysis system of landslides has been developed which is explored on the basis of software MAPGIS. This paper deals with the risk zonation of the regional landslide hazards of China supported by this system, and adopts information content model in the analysis of geo-hazard, analysis of the vulnerability as well as the risk assessment of the geo-hazard. The result is reasonable and practical to a certaiu degree.
