丰台区水资源耦合配置模型研究

Coupling allocation model of water resources in Fengtai district of Beijing

以丰台区水资源配置系统为研究对象,在分析供需水的基础上,构建双层优化模型,其中从环境角度体现对污染物排放量的严格控制,从经济角度体现区域水资源系统经济效益最大化。最终,体现区域水资源数量和质量的统一和不同需水部门之间的合理配置,并达到环境目标和经济目标的集成化。基于模糊满意度算法求解模型,模型结果表明:丰台区各规划水平年的供水量基本上可以满足各用户的需水要求,其中南水北调工程将在区域水资源配置系统中发挥重要作用。进一步地将双层规划模型和两个传统的单目标优化模型的结果进行对比分析,以期为不同决策者提供的规划方案。

Taking Fengtai district as a study object on basis of analyzing water supply and demand , the paper constructed a bi-level optimization model so as to embody the strict control of pollutant emissions from an environmental point of view ,and the maximal economic benefit of water resources system from an economic point of view .Finally the unity of quantity and quality of water resources and coordinative allo-cation of water resources among multi sectors have been achieved .Also, the integrated targets of economy and environment have been realized .The results show that water supply of each planning year in Fengtai district basically can meet the requirement every consumer .The south-to-north water transfer project can play a significant role in the regional allocation system of water resources .It further compared and ana-lyzed the result between bi-level plan model and the two conventional single-objective models so as to pro-vide decision scheme in different scenirous for different makers .
