基于层次-灰色关联分析法的闪电灾害风险区划
Lightning disaster risk zoning in Cangnan of Zhejiang province based on AHP-Grey relational analysis
摘要
Abstract
Cangnan county of Zhejiang province is chosen as a sample area to establish an effective method of light-ning disaster risk zoning.Monitoring data of lightning occurred in Cangnan during 2007-2011,statistics of lightning disasters and related basic information during 1996-2011 are used to analyze the characteristics of lightning disas-ters in Cangnan by using the method of Analytic Hierarchy Process-Grey Relational Analysis(AHP-GRA).The AHP is used to determine the weight of evaluation index,while the GRA is used to calculate the relational coefficient be-tween different evaluation indexes.The comprehensive weighted relational coefficients are then used to derive a relia-ble lightning disaster risk zoning.The results show that the risk grades in descending order are very high risk zone, including Lingxi town and Longgang town;high risk zone,including Yishan town,Qianku town and Jinxiang town;medium risk zone,including Fanshan town,Mazhan town,Zaoxi town,Qiaodun town; and low risk zone,including Chixi town,Dailing town,Fengyang town.The risk zoning results in Cangnan county are verified through ArcGIS in-formation of actual lightning disasters.The verification result shows that the AHP-GRA method is effective for light-ning disaster risk zoning.This research will provide reference for the planning of lightning disaster prevention and e-valuation of lightning disaster risk for major projects.关键词
