摘要(Abstract)：

【目的】随着长三角一体化发展的持续深入，区域用水压力凸显，探明长三角城市生活用水量的时空变化特征与驱动效应，为控制长三角城市生活用水量和建设节水型社会等工作提供科学依据。【方法】通过空间转移系数将城市分为3类，并结合数据可视化分析生活用水量的时空变化特征，利用LMDI方法探究城市生活用水量变化的驱动效应。【结果】生活用水量转出区包含两个城市；生活用水量稳定区包含6个城市；生活用水量转入区包含33个城市；各省、各地区、各类生活用水的分解结果中，经济效应和用水强度效应的数值分别是所有效应中的最大值和最小值；公共服务用水量各效应的贡献率绝对值都大于居民家庭用水量的各效应的贡献率绝对值。【结论】长三角城市生活用水量在空间上总体呈现“东高西低”的特征，在时间上呈现不断增长的特征；经济效应和用水强度效应分别是促进和抑制生活用水量增长的主导因素；人口分布的变化会带来生活用水量的变化；公共服务用水量对各效应变化的反应更加敏感。
