基于信息量模型的云南禄丰地质灾害风险性评价
Geological hazard risk assessment of Lufeng city in Yunnan province based on Information Model
摘要
Abstract
Lufeng City is located in the central part of Yunnan province,with a complex geological environment.Geological disasters occur frequently in this area,posing a serious threat to the safety of local residents'lives and property.This article takes Lufeng city as the research area,integrates the latest 1∶50 000 geological hazard risk survey data,based on the GIS platform,adopts an information quantity model to construct a risk assessment system based on grids.Different evaluation factors were selected for susceptibility assessment for different types of disasters.On the basis of susceptibility assessment,the cumulative precipitation of the 10-year average flood season months(May October)is selected as the triggering factor for hazard analysis and evaluation.A vulnerability evaluation model for disaster prone bodies was constructed by selecting factors such as the distribution of buildings,population,transportation facilities,and other living facilities.Based on the comprehensive evaluation results of hazard and vulnerability,the risk assessment was completed using matrix analysis method.According to the geological susceptibility degree,disaster bearing body condition,risk grade and geological disaster prevention ability of the study area,the risk zoning of geological disasters in the city is realized.The results show that the area with high risk of geological disasters is mainly distributed along the Longchuan river in Konglongshan town and Tuo'an township,with an area of 290.47 km2,accounting for 8.16％.The medium risk areas were mainly distributed in Gaofeng and Caiyun town,with an area of 2 044.21 km2,accounting for 57.48％.The low-risk areas are mainly distributed in the gentle terrain areas from Tuo'an township to Gaofeng,Jinshan and Zhongcun township,with an area of 1222.05 km2,accounting for 34.36％.The evaluation results can provide a basis for geological disaster risk in Lufeng city,and provide ideas and references for other areas to carry out evaluation.关键词
