摘 要:惠水地处扬子准地台黔南台陷贵定南北向构造变形区,为评价研究区地质灾害易发性,在总结前人研究成果的基础上,选取坡度、地层岩性及土体结构、斜坡结构、新构造运动与地震、人类工程活动、斜坡高度、降雨、斜坡变形破坏情况等作为评估因子,采用GIS与层次分析法耦合技术,完成地质灾害易发性分区定量分析.研究结果表明,研究区可划分4个高易发区、6个中易发区,其中,涟江街道、濛江街道、好花红镇、芦山镇、断杉镇及部分王佑镇,点密度为0.058个/km^(2);王佑镇,点密度为0.071个/km^(2);雅水镇、断杉镇及部分羡塘镇,点密度为0.035个/km^(2);摆金镇和岗度镇,点密度为0.035个/km^(2).研究成果可为惠水县防灾减灾、经济发展、城镇规划提供科学依据。Huishui is located in the Guiding north-south structural deformation area of the Qiannan depression,Yangtze metaplatform.In order to evaluate the susceptibility of geological disasters in the study area,based on the summary of previous research results,slope,stratigraphic lithology and soil structure,slope structure,new tectonic movement and earthquake,human engineering activities,slope height,rainfall,and slope deformation and damage were selected as evaluation factors.GIS and Analytic Hierarchy Process coupling technology were used to complete the quantitative analysis of geological disaster susceptibility zoning.The research results showed that the study area can be divided into 4 high susceptibility areas and 6 medium susceptibility areas,including Lianjiang street,Mengjiang street,Haohuahong town,Lushan town,Duanshan town,and some Wangyou town.The point density is 0.058/km^(2);Wangyou town,with a point density of 0.071 per km^(2);Yashui town,Duanshan town,and some Xiantang town have a point density of 0.035 points/km^(2);The research results of Baijin town and Gangdu town have a point density of 0.035 points/km^(2),which can provide scientific basis for disaster prevention and reduction,economic development,and urban planning in Huishui county.
