摘　　要：在阐述地质灾害区划涵义和建立评价指标体系重要性的基础上,较为系统的说明了评价指标体系建立的原则和方法,并结合绵阳市地质灾害分布与地质环境条件之间的关系,建立了绵阳市地质灾害易发性区划的评价指标体系,最后,应用层次分析法确定了各评价指标的权重,得出降雨量指标在地质灾害易发性区划中的作用最为显著,权重值为0.253 3,其次为地质灾害分布密度指标,权重值为0.200 0。Based on expounding signification about zoning of geological hazard probability of occurrence and importance of establishing system of evaluation index,the text systematically expatiates principle of establishing system of evaluation index. Simultaneously,in the light of the principle and the relation between distribution of geological hazards and conditions of geological environment,the text establishes system of evaluation index on zoning of geological hazard probability of occurrence for Mianyang city. Finally,the text applies the analytic hierarchy process to ascertain weight of evaluation index,and comes to the conclusion that weight of rainfall index is maximal and the next is distribution density of geological hazards index,and their values of weight respectively are 0. 253 3 and 0. 200 0.
