Study on Risk Assessment of Rocky Desertification from the Perspective of Disaster System——A Case Study of Dafang County in Guizhou Province
摘要
Abstract
Rocky desertification risk assessment is the basic work for risk management of rocky desertification in Karst ecological vulnerability areas.This research work is based on the theory of regional disaster system,constructed the risk assessment model from three dimensions of the disaster environment,hazards and exposure,and select NDVI,land use type and slope to carry out comprehensive risk assessment of rocky desertification in Dafang County in 1988,2001,2009.The results showed that the rocky desertification risk spatial pattern of the three periods is similar,the high risk region is mainly distributed in the southeast and north central in Dafang County,and the risk of 2009 is minimum.关键词
