Abstract:

The Hangjiang Basin is a pilot basin for implementing the stringent water resources management system in China, so the research on water supply and demand condition, and the implementation scheme of total water-use control index in the basin has important guiding significance. Based on the water resources bulletin of the Hanjiang River Basin, firstly, the evaluation index system on total water-use control index is established. Then, through analysis on water resources supply-demand situation, water-use efficiency as well as comparison between the  water-saving level of different localities in the basin and that of developed countries, the water-consumption level in the basin, difference of water saving amount in various places, water saving potential compared with the developed countries, as well as the localities and industries to be strengthened in water resources management, are determined. It is concluded that in order to maintain the sustainable development and water use safety in the Hanjiang River Basin, water resources management should be strengthened from 2 aspects of increasing supply and water saving, and especially water saving should be concerned in the localities and industries of low water use efficiency.
