我国民用建筑用水量时空差异的驱动效应分析

Analysis of The Driving Effect of The Spatial-temporal Differences in Water use of Civil Buildings in China

近年来,"四节一环保"成为民用建筑高质量发展的新目标,建筑用水与节水成为热点话题,为分析民用建筑用水量关键驱动效应并采取切实有力的节水措施,将驱动效应分解为生活用水强度效应、人口规模效应、生产用水强度效应、产业结构效应及经济规模效应,基于LMDI方法分析得出我国2009-2018年民用建筑用水量的变化特征及驱动效应的时空差异。最后针对如何在发展经济的同时提高民用建筑用水效率提出对策建议,对促进绿色建筑发展及构建节水型社会具有参考价值。

In recent years,"four saving and one environmental protection"has become a new goal of high-quality development of civil buildings.Water use and water saving of civil buildings have become hot topic.In order to analyze the key driving effect of water use of civil buildings and take effective water-saving measures,the driving effect is divided into domestic water intensity effect,population scale effect,production water intensity effect,industrial structure effect and economic scale effect.Based on the analysis of LMDI method,the change characteristics of China’s water use of civil buildings in 2009-2018 and the space-temporal difference of driving effects are obtained.Finally,the paper puts forward countermeasures and suggestions on how to improve the efficiency of water use in civil buildings while developing economy,which have reference value for promoting the development of green buildings and building a water-saving society.
