摘要
应用层次分析和快速聚类法原理,选取社会经济指标、用水指标和水质等5类共10项指标组成评价指标体系,建立咸阳市水资源承载力的综合评价模型,采用聚类分析、层次分析和模糊矩阵的方法进行计算,结果表明:咸阳市水资源承载力不安全系数与较不安全系数之和一直处于0.7附近,较安全与安全系数之和处于0.3附近,且咸阳市水资源承载力安全系数呈现增加态势。在西咸一体化建设规划中通过发展经济、重点水源工程建设和水污染治理可望提高咸阳市水资源承载力。
In order to evaluate the impact of water development on Xianyang City, ten indexes, which were selected based on the analysis of relevant indicators including economic indicator, water use index, bearing capacity index of water and land resources to population, water supply and demand index and water quality indicators, were used to set up the comprehensive evaluation model of Water Resources Bearing Capacity （WRBC） using Cluster Analysis, Analytic Hierarchy Process （AHP） and Fuzzy Matrix. The result shows that the safety factor of the WRBC was only about 0.3, which increases with economic indicator. Against the background of Xian-Xianyang integration, the safety factor of the WRBC will be increased by developing economic and constructing water fountain projects and prevent water pollution.
