基于指标体系的区域水资源合理配置初探

根据评价指标筛选原则,设计了一个反映区域水资源-社会经济系统状况的多层次评价指标体系,建立了水资源合理配置的 GEM-AHP 计算模型.该模型是以水资源利用效果为目标,以社会、经济、资源、环境、技术和管理等领域的多个因子为评价指标,根据方案层与目标层间的关系,将各个子区相对于水资源利用效果的组合权重之比作为各自应分摊的水量之比;再由各子区的人口数量信息,综合确定各自分配的水资源数量.实例研究表明,所建模型对涉及社会、经济、资源、环境、技术和管理等多领域的水资源分配问题具有很好的适用性.

Water Resources Allocation in a Region Based on Evaluation Index System

According to the principles of index screening, a multiplayer evaluation index system reflecting the present state of the water resources-social economic system is established. On the basis of it, a GEM-AHP model for water resources allocation is proposed. In the model provided upward, the utilization effectiveness of water resources in a region is treated as the objective, and many factors involving socity, economics, natural resources, environment, technology, and so on are applied to construct evaluation index system for water resources allocation. According to the relationship between the objective and the plans, the proportion of water resources allocation among cities is determined at last. Case study shows that the method proposed here is suitable for water resources allocation.
