摘　　要：根据2003~2008年的实测资料分析了影响荆江三口分流因素的变化,利用1990~2000年天然径流量过程,基于2002年地形分别计算了调蓄前后荆江三口分流量的变化,获得了三峡水库调蓄作用对荆江三口分流的影响,2008年地形条件下的计算结果表明,荆江三口分流略有增加;这是近期荆江三口分流变化不大的主要原因。Based on the observation data during 2003~2008 years,the main influencing factors on flow diversion of three outlets discharge in Jingjiang are analyzed.The process of natural runoff during 1990~2000 years is used to calculate the change of diversion discharge before and after the Three Gorges Reservoir regulating based on 2002 terrain.The influence of the Three Gorges Reservoir regulating on flow diversion of three outlets in Jingjiang is obtained.The results shows that the flow diversion of three outlets discharge in Jingjiang rises slightly based on 2008 terrain condition,which is the main reason that the flow diversion is little change recently.
