【摘要】 南水北调中线工程河南段受水区水资源优化配置是当地水资源、外调水资源统一、高效、科学管理与调度的基础,本文以水资源优化配置为核心,建立了基于GIS的南水北调中线工程水资源优化配置决策支持系统。论文主要研究了以下三个方面内容:(1)以可持续发展为模型建立的基本原则、以各受水区水资源二次供需平衡为基础,建立南水北调河南段受水区水资源优化配置模型。该模型变量众多,并存在关联约束,具有一般水资源优化配置模型的共同点,又有其特殊性。(2)探讨大系统分解协调技术、交互式多目标求解模型和改进的遗传算法相结合的优化配置模型求解方法。在多目标的处理上,本文提出了基于极值的交互式多目标决策方法,该方法简单、直观、可操作性强,同时考虑了单目标重要程度、单目标满意度、整体目标协调度、决策者参与决策等优点。对通过转换得到的单目标问题采用改进的遗传算法求解,论文对遗传算法的最大的改进是在其中加入了一个基本过程-修正,使遗传算法具有了天然-人工二元结构,从系统的观点来看是合理的。具体实现中,应用搜索种群、参考种群协同进化,在搜索种群中引入不可行度、阈值等概念控制不可解的个数。(3)使用VB+ArcEngine建立了基于GIS的南水北调中线工程水资源优化配置决策支持系统,首次把ArcGIS的网络模型引入到水资源优化配置系统的建立中,真正发挥了GIS的空间分析功能,实现了地理模型和专业模型的无缝结合。更多还原

【Abstract】 It is the basis of unification, high efficiency, management, and scheduling with local water resources and transferring to other localities water resources for Optimal allocation of water resources of the water-received areas in He nan of the middle route of south to North Water Transferring Projection. As the most important part, a GIS-based decision support system (DSS) for optimal allocation of water resources of the middle route of South to North Water Transferring Projection is built.Three mainly problems are researched in this paper, as follows:One, the model of Optimal allocation of water resources of the water-received areas in He nan of the middle route of south to North Water Transferring Projection is built by the basis principle of sustained development and the water resources balance of second supply and need with all water received areas. With many relative variables, it has itself particular parts as well as other similar optimal allocation models of water recourses.Two, the method that the technology of large-scale system decomposition-coordination, interactive multi-objective model and improved Genetic Algorithm (GA) are combined is discussed. For the disposal methods of multi-objective problems, a interactive multi-objective decision-making method, which has some advantages such as simplicity, intuitionistic and good maneuverability and includes single objective important degree, single objective satisfaction degree, whole objective coordination degree and policy-maker, based on extremum is proposed.Single objective problems that are obtained by the way of transforming are solved by improved GA. A basic process, also called amending, is added into GA, which makes it has natural-manual binary structure and is considered to be reasonable from the point of view of system. By use of search populations cooperating with reference population to evolve, the conception, such as infeasible degree and threshold value, etc. is used into search populations to control the amount of unsolved values. GIS-based decision support system for optimal allocation of water resources of the middle route of South to North Water Transferring Projection is established by the use of VB and ArcEngine. The DSS is first introduced into the web model of ArcGIS. It makes the functions of space analysis of GIS and geography model and expert model seamless combination.更多还原
