【摘要】 采用脱钩弹性分析方法,分析安徽省的总用水量和地区生产总值之间的脱钩状态,并评价该省的总体脱钩状况和发展趋势。同时,利用LMDI分解模型把用水量影响因素定义为人口效应、经济水平效应、产业结构效应和水资源利用效应,分析四大效应对用水量的具体影响。结果表明:安徽省水资源利用的脱钩状态是由较差脱钩-弱脱钩-强弱脱钩交替的变化过程,脱钩状况随时间逐渐改善;同时,在四大效应的贡献率分析中,经济发展因素和产业结构因素主要导致了用水量的增加,水资源利用效率因素抑制了用水量,人口对用水量的影响很小。提出了应努力发展资源节约型经济、调整优化产业结构,发展技术提高水资源利用效应以达到强脱钩的目的建议。更多还原

【Abstract】 The decoupling elastic analysis method was used to analyze the decoupling state between the total water consumption and the regional GDP in Anhui Province, and to evaluate the overall decoupling status and development trend of the province. At the same time, the LMDI decomposition model is used to define the influencing factors of water consumption as population effect, economic level effect, industrial structure effect and water resource utilization effect, and analyze the specific effects of the four major effects on water consumption. The results show that the decoupling state of water resources utilization in Anhui Province is a change process of poor decoupling-weak decoupling-strong decoupling, and the decoupling condition gradually improves with time. At the same time, in the analysis of the contribution rate of the four major effects, economic development factors And industrial structure factors mainly lead to an increase in water consumption, water use efficiency factors inhibit water consumption, and the population has little impact on water consumption. This paper made some suggestions for the purpose of developing a resource-saving economy, adjusting and optimizing the industrial structure, and developing technologies to improve the utilization of water resources in order to achieve strong decoupling.更多还原
