【摘要】 本课题以区域供水与水污染控制系统综合规划为核心研究内容，并在针对该问题的研究过程中，采用系统分析及优化理论，以期达到区域供水与水污染控制系统综合规划工作中社会、经济与环境资源的最优化配置。 首先，笔者从规划的五则基本要素出发，提出了区域供水与水污染控制系统综合规划的基本概念，并在总结归纳了供水及水污染控制系统规划历史及现状的基础之上，指出该领域研究中尚存在的某些不足之处； 其次，为改进这些不足，笔者引入具有 Visual Thinking 特征的解释结构模型（Interpretative Structral Modeling）分析方法，对区域供水与水污染控制系统进行问题辨识，并最终构建形成系统综合规划目标体系，从而为综合规划优化模型的建立奠定了理论基础。 再者，针对区域供水与水污染控制系统工程宏观规划具体情况，采用最小二乘法、偏最小二乘法及高斯—牛顿法拟合多种工程费用函数，并通过分析比较选择相应科学合理的函数形式；与此同时，依据水工程传统规划经验，总结归纳出区域水工程设施诸项年运行成本费用计算方法,并尝试建立以水工程年运行成本最低为目标函数，各子系统间水量及水质输入输出为决策变量，水量供需平衡、水质达标及河流环境生态需水量为约束的区域供水与水污染控制系统综合规划优化模型； 最终，在上述研究成果的基础之上，结合实例构建拟规划区域供水与水污染控制系统综合规划的优化模型，并通过调用规划软件 Lingo 中广义简约梯度法(GRG)程序包予以求解，获得了经济与环境效益俱佳的决策方案，从而证明将系统分析与优化理论应用于区域供水与水污染控制系统综合规划实践具有相当的实用性与科学性。更多还原

【Abstract】 The research is mainly about integrated planning for regional water supply andwater pollution control system. To reach the optimum distribution for the resource ofmanpower, economic and environment, the theories about system analysis andoptimization are adopted in this research. First of all, based on the five elemental factors of the planning, the concept ofintegrated planning for regional water supply and water pollution control system ispresented. After generalizing and analyzing the history and present study on theplanning for regional water supply and water pollution control system, the existingshortcomings in this research field are pointed out. Secondly, the Interpretative Structural Modeling with Visual Thinking attribute isapplied to modify these shortcomings. In virtue of this method, the regional watersupply and water pollution control system is identified, and the target system forintegrated planning is also established. By doing this, the theoretical basis is preparedfor the establishment of the optimization model for integrated planning. Thirdly, considering the specific situation of the macro-planning for regional watersupply and water pollution control system, the methods of least squares, partial leastsquares and Gauss-Newton are used to fit the diversiform engineering cost function.After analyzing and comparing the fitting results, the appropriate functions areconcluded. At the same time, according to the experience of conventional planning forwater engineering, the calculation means of annual running costs for regional waterengineering facilities are summarized. The optimization model for integrated planningfor regional water supply and water pollution control system is also established,which object function is the lowest annual running costs of water engineering,decision variables are input and output of water quantity and quality amongsubsystems, and bounds are the balance of water supply and demand, water qualitymeeting the Standard, and ecological water demands in river environment. In the end, based on the above research, an optimization model for integratedplanning for regional water supply and water pollution control system is establishedcombining an actual case. By calling the program GRG in the planning soft Lingo, theresult and decision scheme with good economic and environment returns areaccomplished. This proved that applying the theory about system analysis and<WP=5>optimization to the integrated planning practice for regional water supply and waterpollution control system is practicable and scientific.更多还原
