摘　　要：为了建立和探索区域生态地质环境的评价体系,该文以饶河边疆区为例,利用遥感数据提取相关生态环境信息,选取地形坡度、土壤侵蚀强度、土壤退化因子、植被覆盖度、土地利用类型、地质剖面结构、工程地质岩性性状、地貌特征类型等8个指标因子构建生态地质环境分区评价的指标体系,通过层次分析法确定各个指标因子的权重,借助隶属函数将各个因子图像生成对应级别的模糊栅格图像,建立了基于GIS系统的生态地质环境质量综合评价模型,较好地区分了研究区生态地质环境的相对稳定程度,为相关生态地质环境评价方法研究提供参考。In order to establish and explore the evaluation system of the regional eco-geological environment, the paper taking Raohe district as the study area, selected eight index factors including slope, soil erosion, soil degradation factor, vegetation fractional cover, land use types, geological section structure, engineering geological properties, and landform types and so on to construct the indicator system by using RS and GIS techniques. Through determining the weight of each index by AHP, and producing the fuzzy raster image corresponding to the formation of each factor by the membership function, the comprehensive assessment model of eco-geological environment quality was established, which would classify the degrees of stability efficiently, and provide a reference for related study.
