摘要
为探讨广州市产业用水的变化规律及其与各影响因素间的演变驱动机制,利用KAYA恒等式及LMDI分解法将产业用水的影响因素分为经济发展水平、人口规模、用水效率、产业结构等,分析各因素对广州市2000—2015年产业用水量变化的效应。结果表明:经济发展效应和人口规模效应分别是促进广州市产业用水量增加的主次因素,其累计贡献值分别为85.38亿、45.83亿m^(3);用水效率效应和产业结构效应分别是抑制广州市产业用水量增加的主次因素,其累计贡献值分别为-117.89亿、-25.47亿m^(3)。
In order to explore the change law and driving factors of industrial water use in Guangzhou,this paper divides the influencing factors of industrial water use into economic development level,population size,water use efficiency and industrial structure by the Kaya identity and Logarithmic Mean Divisia Index(LMDI),and analyzes the effects of various factors on the changes in industrial water use in Guangzhou from 2000 to 2015.The results show that:The economic development effect and population size effect are the primary and secondary driving factors for the increase on the industrial water use in Guangzhou,with cumulative contribution values of 8.538 billion m^(3) and 4.583 billion m^(3),respectively;The water use efficiency effect and industrial structure effect are the primary and secondary inhibiting factors for the increase on the industrial water use in Guangzhou,with cumulative contribution values of -11.789 billion m^(3) and -2.547 billion m^(3),respectively.
