Abstract

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
