广西西江流域及主要支流水量分配方案分析

Analysis of water distribution scheme for Xijiang River Basin and its main tributaries in Guangxi

以水利部分配给广西的流域水量控制指标及各市用水总量控制指标为依据,统筹考虑调入与调出、河道内与河道外用水、用水与消耗等关系,开展广西西江及其主要干支流水资源供需平衡和水资源配置分析,合理确定本流域地表水资源的可分配水量。并综合考虑流域内区域间用水关系,依据水资源配置成果,按照水量分配的原则,合理确定广西西江流域及主要支流供各市河道外利用的地表水用水量份额。

Based on the water quantity control index of the river basin and the total water consumption control indexes of various cities allocated by the Ministry of Water Resources to Guangxi,taking into account the relationships between water inflow and outflow,water use within and outside the river channel,water use and consumption etc.,analysis was made on the supply and demand balance as well as the allocation of water resources for Xijiang River Basin and main tributaries in Guangxi,so as to reasonably determine the distributable water quantity of surface water resources in the basin.The inter-regional water use relationship in the basin was considered comprehensively.On the basis of the water resources allocation results and according to the principles of water quantity distribution,the share of surface water use outside the river channel of Xijiang River Basin and its main tributaries was determined for each city in Guangxi.
