基于供需平衡和用水效率模型的节水效益分析

Abstract Water conservation is an action that comprehensive measures of engineering technique economy and management are takento ensure the rational use of water improve the use efficiency of water and reduce invalid loss. Under the current conditions of watershortage and increasing serious water pollution water conservation is a strategic infrastructure project for the exploitation and use of waterresources. Evaluation system model is established by water supply and demand ratio (R1) and water-saving benefit ratio (R2). The twoaspects of evaluation factors could get the level value of water-saving benefit and they are both independent parameters so this model hashigh reference value.院供需平衡 节水效益 分析Key words supply and demand balance water-saving benefit analysis中图分类号院TU991.64 文献标识码院A 文章编号院1006-4311（2014）01-0304-020 引言节约用水是在不降低经济社会发展能力和人民生活质量的前提下，还要确保合理用水的情况下，以提高水资源利用率，减少无谓的损耗为目的，所根据一些具体的功能 技术和管理等各项综合措施的行为。在目前水资源短缺和水污染日趋严重的条件下，节约用水作为水资源开发利用的一项战略性基础工程，是解决水资源供需矛盾的根本出路，也是实现社会经济可持续发展的重要条件。1对
