摘　　要：针对传统评估系统没有统一定量标准,受主观认识影响较大的问题,该文以川西藏区五县为研究区,筛选地形地貌、植被盖度、水土流失、土地覆被、地质灾害、地球化学数据、矿产开采等13种主控因素,借助ArcGIS空间分析和Matlab数学建模功能,构建基于GIS的GA-BP模型(即遗传算法优化BP神经网络),对研究区地质生态环境进行非线性定量评价;采用混合编程实现超大浮点栅格矩阵在不同软件平台间相互传递处理,完成GA-BP评估系统设计;通过回判检验与AHP法结果进行对比分析,凸显GA-BP模型的优越性,为研究矿产开发下非线性的地质生态环境问题提供一种较新颖的、行之有效的方法。This paper took 5 countries of Sichuan as study area,based on factors of remote sensing,vegetation cover,land use type,geological hazards,field sampling geochemical data,mineral resources exploitation and combined with the spatial analysis function of ARCGIS and programming modeling capabilities of MATLAB,finished nonlinear intelligent quantitative evaluation of geo-ecological environmental assessment in this area by the model of GA-BP（genetic algorithm BP neural networks）,and contracted the outcome with AHP,formulated the superiority of GA-BP.This research may provide the beneficial reference for nonlinear geo-ecological environmental assessment.
