基于供需平衡和用水效率模型的节水效益分析

节约用水是在确保合理用水,以提高水资源利用效率、降低无效损耗为目的,所采取的工程、技术、经济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,通过水资源供需比(R1)和节水效益比(R2)两方面评价因素来建立评价系统模型,可得到节水效益的水平值,而两者均为独立参数,减少关联因素的影响程度,此模型评价具有较高的参考价值。

Water-saving Benefit Analysis Based on the Supply and Demand Balance and Water-using Efficiency Model

Water conservation is an action that comprehensive measures of engineering, technique, economy and management are taken to ensure the rational use of water, improve the use efficiency Of water and reduce invalid loss. Under the current conditions of water shortage and increasing serious water pollution, water conservation is a strategic infrastructure project for the exploitation and use of water resources. Evaluation system model is established by water supply and demand ratio （RI） and water-saving benefit ratio （R2）. The two aspects of evaluation factors could get the level value of water-saving benefit, and they are both independent parameters, so this model has high reference value.
