四川省都江堰市龙池地区群发性泥石流物源敏感性分析
Sensitivity Analysis on Mass of Debris Flows on the Longchi Region,Dujiangyan, Sichuan Province
摘要
Abstract
Wenchuan earthquake changed the geological environment of the southwest mountainous, effect of geological disasters produced and under the extreme weather on August 13, 2010 and August 19 led to many outbreaks of mountain flood and debris flow, including Dujiangyan Longchi area of mass outbreak of debris flow. By u-sing AHP-Information method, Longchi area is selected as the research object to analyze the source material sensitivity of debris flow three conditions. Eight factors including roads in affected zone, elevation, slope, slope, vegetation coverage, the river impact are selected and subdivided into 37 levels. A sensitivity weight is set for each grade and ARCGIS platform is used to generate high, medium and low sensitive zoning maps. The results of the e-valuation supplied basis for the possibility of debris flow in the future, and debris flow channels needed to be monitored and constructed are pointed out.关键词
