摘　　要：针对新疆地区岩金类矿山开采导致的地质环境问题,采用Fisher判别分析方法对矿山开采后地质环境影响程度进行分类评价。选取地质灾害、含水层破坏、地形地貌景观破坏、土地资源破坏和地质环境治理难易程度等5项指标作为判别因子,以新疆地区5家岩金类矿山的37个评价单元作为样本,建立了新疆岩金类矿山地质环境影响程度评价的Fisher判别模型,利用回代估计方法对建模数据进行逐一检验,正确率达100%。利用该模型对新疆萨尔托海金矿进行矿山地质环境影响程度判别分析,分类结果与实际分类结果完全一致。研究结果表明,Fisher判别分析法用于新疆岩金类矿山地质环境影响评价效果良好。在分类结果的基础上,提出了相应的防治措施建议。To analyze the geological environment problems caused by mining of rock gold mines in Xinjiang, this paper used the Fisher discriminant analysis method for the classifications about the geological environment impact assessment. Selecting geological disasters, aquifer breakage, landforms landscape devastation, destruction of land resources and difficulty of geological environment governance as the discriminant factors, taking 37 evaluation units from 5 rock gold mines in Xinjiang as study samples, the paper established the Fisher discriminant model of geological environment influence evaluation in Xinjiang rock gold mine. Every sample was tested by using resubstitution method accordingly, and the accuracy was 100 %. The geological environment impact identification and classification of Saertuohai Gold Mine are analyzed by using this model, classification results in complete accord with the actual conditions. The results showed that the prediction model of Fisher discriminant analysis was an efficient method to solve the prob- lem of evaluating the rock gold mine＇s geological environment impact. Finally, on the basis of the classification results, this paper proposed corresponding prevention measures.
