摘　　要：选取2001年以来的我国城市用水数据,从时间和空间尺度上讨论21世纪我国城市用水变化及趋势。研究表明:我国城市用水进入低速增长期,增量主要来自居民家庭用水增长,居民家庭用水已成为我国城市最主要的用水类型;城市用水量变化与其行政级别、经济区位和地理区位的关系密切;城市人均用水量指标将维持缓慢下降趋势,城市人均公共服务用水量指标基本稳定,城市人均生产运营用水指标继续缓慢下降,城市人均居民家庭用水指标稳中有升。Based on the data of urban water consumption in China since 2001, this paper discussed the change and trend of urban water consumption in China in the 21st century in terms of spatial and temporal scale. The urban water consumption of China entered a low-speed growth period, and the increase mainly came from the growth of household water consumption, which had become the most important type of urban water consumption in China. The change of urban water consumption was closely related to its administrative level, economic region and geographical location. Per capita water consumption in cities maintained a slow downward trend. Urban per capita water consumption index of public services was basically stable. Urban per capita water consumption index of production and operation continued to decline slowly, and urban per capita household water consumption index remained stable while rising.
