长江流域水资源供需分析与总体配置布局

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

长江流域水资源总量比较丰沛,但时空分布不均,且利用效率不高,因此,开发潜力较大。在分析长江流域水资源开发利用现状的基础上,进行现状和规划年水资源供需平衡分析,提出流域水资源总体配置布局。通过水资源的合理配置,完善流域和各区域配置格局,到2030年,长江流域水资源开发利用率将达28%,既能满足流域内供水需求,又可为全国范围水资源配置提供必要水源。

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.
