多沙河流区水资源合理配置模型及应用

分析总结了水资源配置理论的发展历程,结合目前比较成熟的理论,建立了多沙河流区水资源合理配置模型,详细阐述了该模型的约束条件和初始条件.其中水库运行规则约束和引提水工程运行规则约束是针对多沙河流地区的约束条件,考虑了含沙量变化对水资源利用的影响,更好地反映了多沙河流区的水资源利用的实际情况.同时,模型结合了水循环系统和水环境系统的分析,保障了社会经济系统与生态环境系统的协调和统一.将该模型应用于延安地区,从配置结果可以看出,多沙河流区水资源合理配置模型为未来合理分配水资源,提高单位水的效率和效益产出提供了科学的决策依据,从而可以提高区域水资源的利用水平.

Model of rational water resources allocation in sandy river areas and its application

The history of water resources allocation theory is summarized;combined with well-developed theories,the water resources allocation in Yan'an City, which is the representative areas of the sandy river areas in China,is researched. The model of water resources allocation in sandy river area has been established;and the features and the measures of allocation have been analyzed. The rule of reservoir operation and the rule of pumping engineering are added in this model; the effect of sand content on water resources development has been considered; so the actual condition has been reflected suitably. Meanwhile, the analysis of water cycle system and water environment system have been combined in this model; it ensured the harmony between social-economy system and eco-environment system. Based on this, the rational water resources allocation for Yan'an City has been completed; and the results are also supplied. It can be useful to make the scientific decision. Finally,some proposals for rational water resources allocation are proposed.
