摘要/Abstract

摘要： 综合考虑经济发展水平、人口规模、产业用水效率及水资源开发利用程度等因素,建立全要素分解模型和运用LMDI分解方法对1995—2012年乌鲁木齐市用水过程的驱动因素进行分解分析.结果表明: 经济发展水平与用水强度是乌鲁木齐市用水总量变化的决定因素;产业用水结构、经济发展水平、用水强度是影响乌鲁木齐市用水效益变动的决定性因素.产业结构调整和产业技术升级对用水总量增加有一定抑制作用,但作用不强.人均供水量的增长在一定程度上对资源利用效率变化起到抑制作用.

关键词: LMDI分解法, 用水效率, 用水总量, 乌鲁木齐市

Abstract: Urumqi was selected as the object for this study. Through constructing an all-factor decomposition model, Logarithmic mean Divisia index (LMDI) decomposition method was used to conduct decomposition analyses on the factors that caused the change process of water resource utilization in Urumqi from 1995 to 2012. The results indicated that economy development level and water use intensity, and the effects of industrial water use structures, economy level, and water use intensity were the determinant factors that influenced the water use consumption and efficiency, respectively. The adjustment of industrial structures and the upgrading of industrial technologies caused certain inhibitory effects on the total water consumption, but these effects were not strong. The amount of water supply per capital had inhibitory effects in certain extent on water resource utilization efficiency.

Key words: LMDI decomposition method, water use efficiency, total water consumption, Urumqi
