北京市工业用水节水分析及工业产业结构调整对节水的贡献

Analysis of industrial water saving and contribution of industrial structure adjustment to water saving in Beijing City

在分析20世纪90年代北京市工业及主要耗水行业节水特点的基础上,重点研究了产业结构调整对节水的作用,并以定量的形式计算出在不同时间段工业产业结构调整对节水的贡献率。1990—1994年间工业产业结构调整对节水的贡献率为29.5%,1994年以后比重逐渐上升,1998—2000年间比重已达到46.1%,表明1990—2000年间产业结构调整对北京市工业节水的贡献率呈上升趋势。

The article analysed water-saving characteristic of the industry of Beijing, then researched the function of industrial structure adjustment on economizing water, It is calculated with quantitative form that the contribution rate of water saving in the industrial structure adjustment during different periods. The result indicates that industrial structure adjustment presents the rising trend of the contribution rate of water saving during 1990—2000 years. the contribution rate of water saving is 29.5% during 1990-1994 years, while it is 46.1% during 1998—2000 years.
