Abstract :
The prevalent water problems like quantity shortage, environment pollution and ecological damage restrict urban sustainable development. Unreasonable water utilizing causes conflicts between artificial water cycling system and natural cycling water system, which turns out to be the source of urban water problems. To find ultimate solutions to the water problems and the way of sustainable water utilization, artificial water cycling system with the whole urban water ecosystem is analyzed. After a comparative analysis of urban water ecosystem and steady natural ecosystem, unsmooth flowing and unbalanced in-out of matter is put forward as the inducement of water problems. It is quite necessary to strengthen wastewater-disposal making it accord with exploitation and using, and to strengthen water renewal forming efficient circulation. In all, water utilizing model should be completed. Reduce, reuse, recycle principle can be applied to promote water cycling efficiency. For further study wastewater can be utilized as resources with technical innovation.
