Risk Assessment and Zoning of Mountain Torrent Disaster Based on GIS in Jiangxi Province
摘要
Abstract
Based on the characteristics of mountain torrent disasters in Jiangxi Province and systematic theory of flood disaster,we selected 9 risk assessment factors to set up the index system of mountain torrent disaster ac-cording to the trigger factors of flood,underlying surface environment and characteristics of disaster-bearing body. Afterwards,we determined the weight of each factor by analytic hierarchy process (AHP).With the support of GIS technology,we made a quantitative analysis for mountain torrent disaster of Jiangxi Province and map the risk zon-ing.The survey data of historic mountain torrent disaster in Jiangxi Province were used to verify our quantitative a-nalysis results.Result of verification showed that the accuracy of risk assessment of mountain torrent disaster is a-round 73%,which confirmed high reliability and applicability of the approach and risk assessment model used in this study.Based on the mapping of mountain torrent disaster risk assessment,statistical analyses were made ac-cording to different administrative areas,basins and morphologic regions,which are vital to the prevention and management of mountain torrent disaster in Jiangxi Province.关键词
