Regional rainstorm geological disasters evaluation based on matter-element model

Rainfall, especially rainstorm is one of most important triggering factors to the activities of geological disasters, Which has brought great losses to people's life an property. In the support of GIS technology, taking Hubei Province,China as study area, based on detailed analysis of the geological disasters influence factors, this article imported matter-element comprehensive evaluation model to evaluate regional rainstorm geological disasters. Results indicated that high-risk area of geo-hazards mainly concentrated in Northwest, Southwest and Southeast of Hubei, middle-risk area roughly distributed in west and east and low-risk area mainly in central and most parts of the Northeast. Research showed the matter-element comprehensive evaluation model theory was simple, easy to operate and had a high degree of quantitative, which has broad application prospects in zoning and evaluation of regional meteorological disasters.
