多目标优化方法在区域水资源优化配置中的应用——以唐山市为例

On application of optimum urban water resources distribution method in the case for Tangshan City

水资源供需矛盾日益加剧,如何优化配置区域内有限的水资源已成为水资源规划与管理研究中的热点。本文在考虑不同水质和水源的基础上,研究了决策变量的约束条件,综合考虑不同用水户的用水效益,采用工业、生活、环境和农业多目标优化的方法,按照决策者的不同意愿,给出不同的配置方案,即一系列非劣解集。通过调用Matlab优化工具箱中的函数对其进行求解,给出了5种不同的水资源优化配置方案,能够合理配置唐山市区内有限的水资源,使得该区域内环境、社会与经济协调发展。

The present paper aims to introduce the authors＇ research on the approach to optimum distribution of the limited water resources in the urban areas by taking Tangshan as a case study. Based on the different grades of water quality and water resources, this paper has studied the decision-making variable＇ s restrained conditions and applied multi-purposed optimization formula in distributing the city＇s limited water resources to mitigate the contradictions and conflicts between water supply and demand and ensure its harmonious development. The so-called multi- purposed water-distribution optimization means the greatest benefit to be brought to the water consumers, including those of industrial and agricultural development, householdliving and the eco-environment protection, etc. It is well known that the existing limited water resources are not enough to satisfy their demands. Carefully studying the goal-attaining function of Matlab toolbox and applying different optimum scenarios, this paper has analyzed and put forward different optimization scenarios in accordance with their objective needs, so as to promote the harmony and sustainable development of our society, eco-environment, and the national economy by taking Tangshan city as a sample. And, finally, the paper has given further discussion on more details on the proper distribution problem.
