渭河流域关中段工业用水效益分摊系数及效益的时空变化研究
Temporal and spatial variation of benefit-sharing coefficient and efficiency of industrial water in the Guanzhong section of Weihe River Basin
摘要
Abstract
In order to illustrate the importance of water in the industrial production,the emergy analysis method is used for computing the industrial water benefit-sharing coefficient in the Guanzhong section of Weihe River Basin and its changes in time and space scale is analyzed,with the calculation results showing that the Guanzhong section of Weihe River Basin of industrial water benefit-sharing coefficient continues to decline,and that the average value is 4.2％ for many years.The Guanzhong section of Weihe River Basin industrial water benefit-sharing coefficient for many years with an average of 4.2 ％,Weinan City is 3.7 ％,Tongchuan City is 2.9 ％,Xianyang city is 5.2％,Baoji City is 2.6％,and Xi'an City is 6.4％,which is mainly caused by the different proportion of input elements in industrial production in each area.The benefits of pre-stere water and benefit in the middle of the Weihe River Basin show a continuously increase with the time,and a small change in the middle.关键词
