基于模糊综合评价法的泥石流风险评价
Assessment on Debris Flow Risk based on Fuzzy Comprehensive Evaluation Method
摘要
Abstract
Vulnerable degree factors are added into the existing fuzzy comprehensive evaluation model of deb-ris flow risk to establish for the first time the comprehensive evaluation model of debris flow risk ambiguity.Based on this model,risk assessment is done to five debris flows in Shennongjia Forest Region,and the results show that fuzzy comprehensive evaluation model could be used in debris flow risk assessment.According to the problem———the calculation results of fuzzy comprehensive evaluation model can reflect the size of the risk,but is unable to re-flect the risk characteristics,and combing fuzzy comprehensive evaluation method with the plane coordinate,a new debris flow risk assessment method———fuzzy coordinate method is put forward.Fuzzy comprehensive evaluation on risk and vulnerability of a debris flow are done by the new method,with the evaluation results as coordinate points, define the distance from coordinates to the origin point as the risk degree,the evaluation results can reflect the risk and performance of vulnerability by using the two-dimensional characteristic of plane coordinate and the specific characteristics of the debris flow risk can be expressed.关键词
