基于投入产出分析法的节水经济效益分析

Analysis of water-saving benefits based on input and output method

基于投入产出分析方法,考虑节水调节因素,建立水资源投入产出关系表和水资源投入消费关系表,对节水调节的经济效益进行定量分析。分析结果表明,在水资源供给总量一定的前提下,发展节水调节系统可持续提高社会产出,是维护区域水环境经济系统可持续发展的重要手段。

Based on the input and output method,some charts for water resources input and output as well as for water resources input and consumption are established by taking water-saving into consideration.Quantitative analysis is carried out.The results show that with the development of water-saving system,the social production increases continuously under a definite total amount of water resources supply.It's an important way to keep the sustainable development of economy system of regional water environment.
