蔚汾河流域水资源多目标优化配置方法探讨

Exploration of the Muti-objective Optimized Allocation Approach of the Water Resources in Weifen River Basin

随着社会经济快速发展和水环境持续恶化,蔚汾河流域水资源供需矛盾日益加剧。本文对蔚汾河流域有限水资源的优化配置方法进行探讨,并对流域水资源进行可持续开发和利用,有利于促进人类可持续发展。在调查该流域不同水质水源基础上,本文研究了决策变量的约束条件,采用生活、农业、工业/建筑业、第三产业和生态环境多目标优化方法,结合决策者不同偏好,得出了几种不同的配置方案。通过调用Matlab优化工具箱中的fgoal-attain函数对该模型进行求解,得到几种不同的水资源优化配置方案,符合蔚汾河流域可持续发展的规律,能使该流域内环境、社会与经济协调发展。

Water resources of Weifen drainage basin are serious out of balance day by day,along with the social economic development growing rapidly and aquatic environment keeping deteriorating.The paper aims to introduce a study on the approach to optimal allocation of the limited water resources in drainage basin,develop and utilize water resources in drainage basin which promote the human being sustainable development.Based on the different grades of water quality and water resources,the paper studied the decision-making variable＇s restrained conditions and applied multi-objection optimization formula in distributing the limited water resources in Weifen drainage basin to mitigate the contradictions and conflicts between water supply and demand,and ensure its harmonious development.The multi-objective optimal allocation of water resources means the greatest benefit to be brought to the water consumers,including industrial and agricultural development,tertiary development,household-living and eco-environment and etc.Studying the goal attaining function of Matlab toolbox and applying different optimum scenarios,the paper analyzed and put forward different optimization scenarios in accordance with development of Weifen drainage basin＇s society,eco-environment,and the national economy.Finally,the paper has given further discussion on more details on the proper water resources distribution problem.
