【摘要】 城市建设用地地质环境质量评价是进行城市规划和建设用地选址的基础。通过对九江市环境地质、水文地质资料进行分析,结合野外地质调查,把坡度、基岩埋深、地质灾害等9项指标选定为评价因子,选定其中的坡度、特殊性土厚和地质灾害为敏感因子;划分了评价因子的等级,对评价区域进行了单元划分;选择了灰色聚类模型进行地质环境质量评价,并吸收了敏感因子-模糊聚类模型的优点。结果表明:灰色聚类法的评价结果与实际情况符合较好,适于对九江市建设用地进行地质环境质量评价,其结果能够达到为九江市的规划建设提供地质环境信息的目的。更多还原

【Abstract】 Geological environmental quality evaluation of urban construction land - use is the foundation of urban planning and site choice of construction land - use.Chooses nine indexes such as slope,geologic hazards and so on as the evaluation factors,and divides the evaluation factors’ class and select the sensitive factors which are slope、especial soil thickness and geologic hazard on this foundation,through analyzing the background of environmental geology,hydrological geology and field geological investigation of Jiujiang.Then divides the units in the evaluation area,and chooses the grey clustering method to evaluate the geological environmental quality,during the evaluation process adopts the sensitive -factors fuzzy clustering model’s advantage.Finally,it concludes that the grey cluster evaluation result is better to accord with practical situation,suit to evaluate the geological environmental quality of construction land - use in Jiujiang and can achieve the aim of providing geologic environmental information for Jiujiangs planning and construcion.更多还原
