【摘要】：城乡统筹供水是发挥城市供水优势、带动农村地区供水事业发展的有效途径。在实践上,城乡统筹已经在部分地区取得了成功。如何利用这些成功实践积累的宝贵经验,进一步推动城乡统筹供水系统建设从而改善农村供水服务,是实践和理论研究领域均十分关心的问题。通过文献梳理和项目调研,总结了城乡统筹供水系统建设的典型模式,提出了利用典型模式指导城乡统筹供水项目的规划设计的观点,并结合供水系统目标,构建了城乡统筹供水系统建设方案比选方法。研究成果有望促进城乡统筹供水系统进一步推广和应用。从建设实践来看,城市管网延伸模式、乡镇建配水站模式和城乡联网供水模式是城乡统筹供水建设成功的典型模式。三种模式的特点不同,适用的对象也存在差异。对拟采用城乡统筹供水的区域而言,可以利用典型模式,指导建设方案的规划设计,再通过综合评价,确定最优的建设方案。供水系统建设方案评价应该围绕系统在经济性、可靠性和可持续性等方面的目标展开。对系统经济性、可靠性和可持续性等目标的内涵和影响因素的深入分析,揭示了城乡统筹供水系统建设决策需要考量的主要问题。在此基础上,构建了建设方案综合评价指标体系。针对评价体系中部分指标综合性强、难以具体量化的困难,采用了模糊软集合综合决策方法,使定性指标向定量的转化,并最终实现建设方案的综合评价。案例分析展示了典型模式在城乡统筹供水中的作用以及建设方案综合评价方法的使用。
[Abstract]:Urban and rural water supply is an effective way to give full play to the advantages of urban water supply and promote the development of water supply in rural areas. In practice, urban and rural coordination has been successful in some areas. How to make use of the valuable experience accumulated in these successful practices to further promote the construction of urban and rural water supply system and improve the rural water supply service is a problem of great concern in the field of practice and theoretical research. Through literature review and project investigation, this paper summarizes the typical mode of water supply system construction in urban and rural areas, puts forward the viewpoint of guiding the planning and design of urban and rural water supply project by using typical model, and combines with the water supply system goal. The construction scheme of urban and rural water supply system is compared and selected. The research results are expected to promote the further promotion and application of urban and rural water supply system. From the view of construction practice, urban pipe network extension mode, township water distribution station model and urban and rural water supply model are typical models of urban and rural water supply construction. The characteristics of the three models are different, and the applicable objects are also different. For the regions that plan to use urban and rural water supply as a whole, we can use the typical model to guide the planning and design of the construction scheme, and then determine the optimal construction plan through comprehensive evaluation. The evaluation of water supply system construction scheme should focus on the economic, reliability and sustainability of the system. The intension and influence factors of system economy, reliability and sustainability are deeply analyzed, and the main problems that need to be considered in the decision of urban and rural water supply system construction are revealed. On this basis, the comprehensive evaluation index system of construction scheme is constructed. In view of the difficulty that some indexes in the evaluation system are comprehensive and difficult to quantify, the fuzzy soft set comprehensive decision method is adopted to transform the qualitative index into quantitative one, and finally to realize the comprehensive evaluation of the construction project. The case analysis shows the role of typical model in urban and rural water supply and the use of comprehensive evaluation method of construction scheme.
