部门竞争性用水压力量化分析方法及应用
A quantitative analysis method for competitive water pressure in different sectors and its application
摘要
Abstract
Clarifying the competitive water use problem in different sectors is crucial for allocating water resources and eliminating the contradiction between water supply and demand.Based on the relationship between supply and demand of water resources,we discussed how to quantitatively analyze the competi-tive water pressure,and constructed the competitive water pressure index(CWPI).Subsequently,the input-output analysis method was used to quantify the competitive water pressure in different sectors.Taking 2020 as the key research period,we analyzed the competitive water pressure structure in China's industrial sector based on the data of 2012,2015,and 2018,as well as its correlation with water use effi-ciency(WUE),so as to identify its driving mechanism and evolution patterns.The results show that there were nine high CWPI sectors and 5 low CWPI sectors in 2020;during the study period of 2012-2020,most sectors showed a trend of changing from"low CWPI-high WUE"to"high CWPI-high WUE".The economic effect was the main factor driving the increase of competitive water pressure;whereas the industrial structure effect was quite weak.The direct water pressure and indirect demand effect changed significantly with time.关键词
