面向水资源安全的绿洲受水区水资源配置方案评价

水资源安全问题已成为制约克拉玛依市经济发展的重要因素。通过调查克拉玛依市水资源开发利用情况,从空间配置、时间配置、用水配置、水源配置等方面入手,设计两个步骤来解决:(1)选取12个用水指标构建水资源安全评价体系,应用层次分析法构造判断矩阵,并确定各指标因子的权重;(2)拟定各类需水方案、供水方案组合叠加生成调度运行方案,形成水资源配置方案集,并设置各方案的水资源安全评价指标,再运用层次分析法优选WRMM模型配置结果,然后对克拉玛依市2011年水资源安全状况进行评价与分析。结果表明,基于水资源安全评价指标的最佳水资源配置方案8,供水保证率达到100%,水资源开发利用率为57%,灌溉水综合利用系数为0.75,为提高克拉玛依市水资源利用率、保障区域用水安全提供科学依据。

Evaluation of water resources allocation schemes of oasis intake areas based on water resource security assessment: A case study of Karamay city

Water resource security problem has become one of the important factors which restrict the economic development of Karamay.Based on the investigation into the development and utilization of water resources in Karamay,an evaluation index system for water resource security was established.Considering the space,time,water use,and water sources,we took two steps:(1) We selected 12 indexes to build the water resource security evaluation system,and used the analytic hierarchy process (AHP)to build a judgment matrix so as to determine the weight of each factor.(2)We combined various types of water demand and water supply schemes to generate various dispatching schemes,and thus form a water resources allocation scheme set.At the same time,we set up water resource security indexes for each scheme,and used AHP to select the optimum results of the WRMM model.Then we evaluated and analyzed the water resource security situation of Karamay in 2011.According to the water resource security index system,the optimal water resources allocation scheme was Scheme 8,whose water supply guarantee rate was up to 100%,water resources exploitation rate was 57%,and irrigation water utilization coefficient was up to 0.75.This research has provided a scientific basis for utilization of water resources and management of water resource security in Karamay.
