摘要

地质环境质量的综合评价对城市环境管理规划有着重要意义。在系统分析影响咸阳城市地质环境质量因素的基础上

将信息扩散与模糊综合评价有机结合

提出了一种区域地质环境综合评价模型

并对咸阳城市规划区的地质环境进行了综合评价。这种评价模型充分考虑周围土地单元的致灾因子对地质环境质量的影响

并利用专家-层次分析法确定影响因子权重

采用模糊综合评价考虑了多因素对环境质量的影响。

Abstract

Comprehensive evaluation of geological environment is important to urban environmental management and urban planning.Based on the systematic analysis of the chief factors influencing the urban geological environment in Xianyang City and the combined information diffusion with fuzzy integrated evaluation

a comprehensive evaluation model of geological environment was constructed

and then urban geological environment in Xianyang City was comprehensively evaluated.The evaluation model was propounded for regional geological environment by considering the effects of surrounding cells.In the model

the analytic hierarchy process(AHP) was used to found the influence factor weight.The fuzzy integrated evaluation was adopted to determine the effects of various factors on geological environment.
