为了解三峡水库不同调度方式对荆江三口分流量的影响情况,利用三峡水库蓄水运用前1998~2002年三峡逐日入库流量、宜昌站逐日流量与荆江三口5站逐日流量的相关关系,对中小洪水调度模式下( 2010~2013年)荆江三口控制站的逐日平均流量进行天然径流还原计算,并对三峡水库初步设计调度方式下荆江三口控制站的逐日平均流量进行模拟计算,分析比较了正在实施的中小洪水调度方式和初步设计调度方式对三口分流量的影响. 随后根据分析成果,结合三口季节性用水需求,对三峡水库调度方式优化进行了探讨,提出将三峡水库提前至9月1日蓄水,可适当减少三口断流天数.

To understand the influence of different operation modes of Three Gorges Reservoir on division of three channels of Jinjiang River, the reduction calculation of natural runoff of daily average discharge of the controlling station of three channels of Jinjiang River under small-medium flood operation mode(from 2010 to 2013) was conducted, by using daily inflow of Three Gorges Reservoir, daily discharge of Yichang Station and 5 stations of three channels from 1998 to 2002 before the impoundment of Three Gorges Reservoir. The daily average discharge of the controlling station of three channels under the initial designed oper-ation mode of Three Gorges Reservoir is simulated and calculated and the influence of the initial mode and the current mode on division of three channels of Jinjiang River is analyzed. The optimal operation mode of Three Gorges Reservoir is discussed on the basis of the analysis results and by consideration of the seasonal water usage demand of three channels. It is proposed that the im-poundment of Three Gorges Reservoir should be advanced to 1st, September, so as to reduce the zero-flow days of three chan-nels.
