    摘要:

    工业是中国第二大用水户,其节水效果直接关系到中国用水总量控制目标的顺利完成。采用对数平均迪氏指数分解模型(LMDI)对中国2000—2018年工业用水量历史演变的驱动因素进行分解。将情景分析法和蒙特卡洛方法结合,对2019—2030年工业用水量未来演变趋势进行多情景模拟,从而判别最优的工业节水路径。研究发现:工业用水强度下降是促进工业用水量下降的主要因素,经济增长和人口规模扩大是促进工业用水量增加的主要和次要因素,工业化水平对工业用水量演变的促增效应和促减效应均有出现;在不同情景下,工业用水量未来的分布演变趋势存在明显差异,当工业用水强度保持现状情景值,工业化水平、人均国内生产总值和人口保持目标情景值时,为最优的工业节水路径。提出需要大力推进工业节水改造,提高经济增长质量,优化调整工业行业结构,提高人口素质,以推动工业节水。

    Abstract:

    Industry is the second largest water use sector in China, and its water-saving effect is directly related to the successful completion of China’s total water use control target. In this paper, the Logarithmic Mean Divisia Index model (LMDI) is used to decompose the driving factors of the historical evolution of industrial water use in China from 2000 to 2018. The scenario analysis method and Monte Carlo method are combined to predict the future of industrial water use in 2019-2030. Multi-scenario simulation of the evolution trend to determine the optimal industrial water-saving pathway. The study found that the decline of industrial water intensity is the main factor that promotes the decline of industrial water use, economic growth and population expansion are the primary and secondary factors that promote the increase of industrial water use. Both accelerating and decreasing effects of industrialization level on the evolution of industrial water use have appeared. Under different scenarios, there is a clear difference in the future distribution and evolution trend of industrial water use. When industrial water intensity maintains the current scenario value, and industrialization level, GDP per capita and population maintains the target scenario value, considered to be the optimal industrial water-saving pathway. Therefore, this paper suggests to vigorously promote the transformation of industrial water saving, improve the quality of economic growth, optimize and adjust the industrial industry structure, and improve the quality of the population, in order to promote industrial water saving.
