摘要
根据广德县的实际情况,选取5项主要因素为评判指标并将其量化结合在单一准则下计算出各因素的权重,运用模糊综合评判的基本原理对研究区滑坡危险度进行区划,得到高危险度区、中危险度区以及低危险度区三个危险度等次,三区的面积分别约为385.4km2、621.3km2、1158.3km2;得到95%的置信区间分别为(11.82%,23.78%)、(21.62%,35.78%)、(45.7%,61.3%),并对三个危险度区的滑坡灾害特点分别进行了概述。
Based on the practice of Guangde county, five main factors are choose and quantify it, in company with the weight of signal rule＇s achieved, applying principle of fuzzy synthetical judgment to the Guangde landslide hazard Zonation, divide the studying area into three grades： highly hazard Zonation, middling hazard Zonation, lowly hazard Zonation, three hazard zonations area are 385. 4km^2, 621. 3km^2, 1158. 3km^2 respectively, 95% reliability is （11. 82%, 23. 78%）, （21. 62%, 35. 78%）, （45. 7%, 61. 3%） respectively, and landslide character of three hazard zonations is summarized.
