基于层次分析法的奉节县城地质环境承载力评价

Assessment of Geological Environment Carrying Capacity of Fengjie County Based on AHP

在考虑地域地质特点基础上,首先构建奉节新县城地质环境承载力评价指标体系,然后运用层次分析法确定出评价指标权重,借助GIS技术对评价指标图层提取、分析、处理,最后得到奉节县城的地质环境承载力分区图。研究成果可为奉节新城今后的建设规划提供科学依据,并可为类似库区迁建城市以及丘陵山区的城市建设和地质灾害防治等提供宝贵方法借鉴。

Considering the geological and regional feature, the assessment system of geological environment bearing capacity was established, and the weights assessment indexes were presented by Analytic Hierarchy Process （AHP）. Through extracting, analyzing and processing the assessment indexes by means of GIS, the zone map of geological environment bearing capacity of Fengjie County was obtained. The results provide a scientific evidence for the construction plan for Fengjie new town and provide a reference for the relocated cities of similar reservoir areas and city construction of hilly and mountainous areas.
