基于层次分析法对扬州市深层地下水资源评价

Evaluation of deep groundwater resources Yangzhou based on AHP

针对我国目前缺少有效评价城市地下水资源脆弱性的问题,本文以扬州市规划区(广陵区、邗江区)为例进行地下水资源脆弱性评价探讨,结合其地下水资源的特性、水文和地质资料,选取了13个指标构建地下水资源脆弱性评价指标体系,运用层次分析法确定指标权重并进行一致性分析。结果表明,扬州城市规划区深层地下水脆弱性等级为Ⅱ-Ⅲ级,地下水资源相对丰富。

Vulnerability of groundwater resources is the basis for regional water resources planning and management. In view of the current lack of effective evaluation of groundwater resources, the ground-water resources was evaluated by taking the Yangzhou City Planning Area （ Guangling, Hanjiang Dis-trict） as example. Based on the characteristics of groundwater resources, hydrological and geological data, thirteen indexes were selected as the assessment index system, And the AHP was used to deter-mine the index weight and finish the consistency analysis. The results showed that the groundwater vulnerability grade of Yangzhou urban planning area is Ⅱ - Ⅲ , the groundwater resources are rela-tively rich.
