摘　　要：以江西省九江市修水县1∶50 000地质灾害调查项目为依托,结合修水县区域地质环境条件及地质灾害发育概况,选取了地层岩性、地质构造、降雨量、斜坡结构类型、坡度、坡高、坡向和人类工程活动等8项指标,构成研究区地质灾害危险性评价指标体系,并在层次分析法的基础上,建立了修水县地质灾害危险性评价层次结构模型.通过构造两两判断矩阵,计算得出了各指标的权重值.最后,根据分析结果将研究区划分为高危险区、中危险区和低危险区,并进行了相应的分析与评价,结果表明:层次分析法在该区域地质灾害危险性评价中的应用效果良好,评价结果基本与野外调查结果相吻合,为修水县地质灾害的防治及城镇规划建设提供了可靠依据.Based on the 1：50 000 geological hazards survey project of Xiushui County, Jiujiang City, Jiangxi Province, and its geological environment and status of geological hazards, a risk assessment index system of geological hazards was formulated in the research area with 8 indexes included, namely stratigraphic lithology, geologic structure, rainfall, slope structure type, slope, slope height, slope direction and human engineering projects. Moreover, a hierarchy model of risk assessment of geological hazards in Xiushui County was established by analytic hierarchy process. By constructing a pair of judgment matrix, the weights of each index were calculated. Finally, according to the analysis results, the study zone was divided into high danger zone, medium danger zone and low danger zone, and the corresponding analysis and evaluation were also made. The results showed that the analytic hierarchy process had a good effect on the risk assessment of geological hazards in this area, and the evaluation results were basically consistent with the field survey results, which provided a reliable basis for the prevention and control of geological hazards and the construction of town planning in Xiushui County.
