【摘要】 随着生态小区的不断发展，小区水环境日益受到人们重视。生态小区水环境系统主要由给水排水系统、雨水系统、中水系统、景观水系统以及节水和用水管理等子系统组成。本文以可持续发展思想为指导，从生态学角度遵循整体、协调、自生和循环的原则，建立和评价了生态住宅小区水环境系统的生态循环利用模式。分析了生态小区内雨水和中水利用的可行性，及其利用的主要途径和系统建设模式。根据生态小区水环境系统的规划建设内容，着重对小区水环境系统中的雨水收集利用技术、中水回用技术、景观水水质保持技术、给水排水系统、节水和用水管理措施等方面进行了研究，依据生态小区水环境系统的建设原则和策略，建立了生态住宅小区水环境系统建设模式，对生态住宅小区水的综合利用系统进行了探讨。根据生态住宅小区水环境性能评价指标体系构建的依据和原则，结合合肥市当地水资源状况和气候特点，建立了合肥地区生态小区水环境性能评价指标体系；运用层次分析法和模糊综合评价法分别确定评价指标权重和评价结果，对生态小区水环境系统各方面进行整体评价。根据本文研究建立的生态小区水环境建设和评价方法，应用于合肥市某小区，经过水量平衡分析后，对小区的水环境系统进行设计和技术经济分析评价。结果表明：开发建设生态小区水环境系统，不仅能产生较好的经济效益，而且有巨大的环境、资源、社会效益，适宜在住宅小区内推广应用。更多还原

【Abstract】 Along with the increasing of residential areas, the water environment system, including Water supply and drainage system, Rainwater system, Graywater system, Scenical water system, Water-saving and water management system, is attracting increasing attention.By the guidance of the theory of sustainable development and the principles of holism, harmony, regeneration and circulation, from the standpoint of ecology, the ecological recyling pattern of water environment system in ecological residential area is presented and evaluated. The possibility to make use of rainwater and graywater is discussed in this paper. Techniques for rainwater collection and using, intermediate water reuse, scenical water protection, water-saving in residential area, the establishment of water supplying and drainage system and the management of water utilization are espically discussed. Based on the principles and the analysis of water multi-purpose utilization system in Hefei, the water environment assessment indicators system in Hefei ecological residential area is setted up. The weights of assessment indicators are caculated with AHP, and the comprehensive assessment for indicator system is based on Multilayer Fuzzy Synthetical Appraisement.Based on water quantity balance analysis, a water environment system in an ecological residential area in Hefei is designed. And the corresponding technical, economical analysis and assessment is performed. The results show that the development of ecological recyling system of water in residential areas will have not only a good economic, but also a tremendous environment, resources and social benefits. The system is avalible surely in many residential areas.更多还原
