Abstract
It's the basis of the regional geological hazard assessment of regional geological hazard risk research, and the result can provide foundation for planning of land and resources, selection of important project site, controlling, monitoring, and forecasting geological disaster, developing contingency measures for disaster, and environmental protection. With the development of GIS technology, methods and models of regional geological hazard assessment have made great progress, it gradually change from the qualitative and semi-quantitative to quantitative, systematic, spatial management. This paper proposed a user-oriented, method- oriented, category-oriented system of regional geological hazards risk assessment through discusses the key points of geological hazards risk assessment, and the requirements of geological disaster evaluation system development today. The new evaluation system fit varieties types of geological disaster evaluation in different areas, and it owns a very important practical significance.
