摘　　要：矿产资源地质勘查综合评价的目的是获取评价区的勘查优劣程度和资源保障程度等信息,为提高开发效率、优化开发结构以及矿山环境保护与治理评价等后续工作提供依据。以藏中地区为例,选取了多金属矿、铜矿、钼矿、铬铁矿等9种优势矿种作为主要评价对象,并在分析西藏自治区前2轮矿产资源规划的基础上,划分出33个地质勘查评价单元。综合考虑工作程度、实物工作量、资源储量及质量特征、勘查技术等4类因素,建立了矿产资源地质勘查评价指标体系。将层次分析法(Analytic hierarchy process,AHP)和专家打分法相结合确定各评价指标的权重,采用基于灰色关联度的模糊综合评价模型进行综合评价,为该地区新一轮的矿产资源规划提供参考。The goal for comprehensive evaluation of mineral resources is to obtain the information of mineral exploration and the degree of resources security in the evaluation area so as to provide basis for the following work such as improving development efficiency,optimizing the structure of mineral development,conducting evaluation of mine environmental protection and governance. Taking the middle area of Tibet as the research example,the nine advantageous resources such as polymetallic ore,copper ore,molybdenum core,chromite ore are selected as the mine object of evaluation. The 33 geological exploration evaluation units are divided based on analyzing the existing two mineral resources planning of Tibet autonomous region. The evaluation index system for geology exploration of mineral resources is established by considering the four kinds of factors such as degree of work,physical effort,resources and quality characteristics and exploration technology synthetically. The weight values of evaluation index are calculated by using the analytic hierarchy process（ AHP） and expert scoring method. The fuzzy comprehensive evaluation is conducted by using the fuzzy comprehensive evaluation model based on grey correlation degree so as to provide some reference for the new mineral resources planning in this research area.
