摘　　要：矿山地质调查与评价模型的可靠度对矿山地质环境评价结果质量起着关键作用。本文将加权信息量模型应用于矿山地质环境影评价中,采用判断矩阵间接给出法与层次分析法综合确定指标权重,基于ILWIS软件应用模型进行四川省矿山地质环境影响评价,利用核查矿山对该模型评价结果进行校验,可靠性较高。Mining processes creates a potential negative impact on the geological environment. An effective geological environment assessment rely on the reliability of assessment model. In this paper,we proposed a Weighted Information Model to evaluate the negative impact caused by mining on natural geological environment. The weights of the evaluation factors are obtained through weight matrix and analytic hierarchy process. An GIS platform named ILWIS is used in the case study of mine geological environment impact assessment in Sichuan province. Lots of mines are used to validate the results of the model,which proves that the Weighted Information Model is reliable for assessing the impacts on geological environment caused by mining processes.
