CONSTRAINING FACTORS TO SUSTAINABLE UTILIZATION OF WATER RESOURCES AND THEIR COUNTERMEASURES IN CHINA

This paper discusses the constraining factors to sustainable utilization of water resources in China, and the countermeasures to realize sustainable water utilization. The result of comprehensive analysis shows that constraining factors to sustainable utilization of water resources in China are complicated, including physical geographical factors and socio-economic factors, such as uneven distribution of water resources at temporal and spatial scales,inappropriate institutional arrangement and non-water-saving and non-water-conservation production and life mode.The countermeasures against constraining factors to water resources sustainable development are put forward as follows: 1) using wetlands and forests, and through spatial conversion to realize temporally sustainable supply of water resources; 2) transferring water between basins and areas and developing various water resources in water shortage area; 3) establishing water-saving society; 4) strengthening water pollution control and water resources protection;and 5) establishing unified water resources management mechanism.
