摘　　要：试图通过对关中盆地地下水系统环境演化效应的分析，探讨人类开发活动对生态环境的影响。其方法是在运用模糊数学对地下水污染程度进行分级的基础上，采用单元模糊聚类法对关中盆地潜水赋存的各种环境因素，如含水层的类型、埋藏深度、包气带岩性特征、开发强度以及污染现状的影响等进行系统分析，并建立环境质量模型，进而对盆地内各个地质单元体中的地下水系统区域环境影响，进行综合性的模糊评价。By means of the element fuzzy clustering analysis, the authors analysed various environment factors such as types and buried depth of water bearing layer, rock characteristics of gas wraped zone, development strength and pollution status that bring influence on the storage conditions of Guanzhong basin′s groundwater system. The impacts caused by exploiting acticity of mankind on the environment evolution of groundwater system and the ecological environment was discussed, and further comprehensive fuzzy assessment on groundwater system in each geological element of the basin was conducted.
