| 摘 要： | 大量国内外统计数字表明,我国城市用水结构正在发生新的变化.城市用水总量经过了快速增长期后进入了平缓发展阶段;城市人均综合用水指标虽有较大幅度下降,但仍较部分发达国家平均水平高出1倍以上;单位用水量产生的GDP仅为发达国家的1/6～1/20;供水损失率也较高;节约用水的潜力还很大,用水效率有待提高.

| Abstract: | It is shown by statistics both home and abroad that new changes is happening on water use structure in urban areas in China. Total urban water use enters into a gentle development stage after fast growth. Index of average water consumption per capita has a relatively big decrease in urban areas, but this figure still doubles than average level of some developed countries. GPD generated by per unit of water use is only 1/6 -1/20 of the developed countries. Water loss is also high and water saving potential is huge. There are still room for improvement of water use efficiency. |
