Analysis of supply-demand of water resources in Yangtze River Basin and its general allocation

The total amount of water resources in Yangtze River Basin is abundant, however, its temporal-special distribution is uneven and the utilization efficiency is low, so the development potential is large. On the basis of analyzing the water resources in Yangtze River Basin and its development and utilization situation, we analyze the supply-demand balance of water resources in current year and planning level year, the general allocation of water resources are proposed. The allocation structure of the basin and various areas are perfected through reasonable allocation adjustment. By the year of 2030, the development and utilization rate of water resources in Yangtze River Basin will reach 28%, which can meet the water demand in the basin and provide necessary water resources for water resources allocation in national wide.
