“4·20”芦山地震后的四川地质灾害形势预测与防治对策
Tendency prediction and prevention strategy of geohazards triggered by Lushan Ms 7 earthquake, Sichuan Province, China
摘要
Abstract
A large number of secondary geological disasters were induced by the "4 · 20" Lushan earthquake in Sichuan province.In order to assess the secondary geological hazards,this paper analyzes the effects of topography,geological conditions,earthquakes and drought on debris flow development,and then sets up the assessment indexes.A speedy quantitative assessment of hazards sensibility is carried out using GIS spatial analysis technology.The results indicate that the areas of the high probable,mid-probable,low probable geological disasters in Sichuan province in 2013 are 99 700 km2,66 700 km2,14 100 km2,respectively.The high probable geological disasters will be distributed over the affected areas by the Lushan earthquake and the Wenchuan earthquake,and the drought areas in the south and southeast of Sichuan province.Based on the above,the suggestions of prevention and control are put forward.关键词
