摘　　要：为解决芦苞涌分流量大幅度减小的问题,调查整理了芦苞水闸修建、改建、重建时的过流量资料,分析北江干流石角—芦苞河段河床冲淤演变及其引起的河道水位变化,计算了典型年来流条件下芦苞涌在河床下切前、后分流量的变化。结果表明,芦苞水闸的修建和北江河床下切导致北江向芦苞涌的分流量大幅减少,现状工况(2007年水闸、河床下切后)与最初天然工况(无闸、河床下切前)相比,在97%典型年来流条件下年均分流量减少约96.5%。In order to solve the problem due to the greatly reduced shunt volume from North River to Lubao Stream, flow data of Lubao sluice during the construction and reconstruction was collected and investigated. By analyzing the water level variation of Shijiao Station caused by riverbed entrenchment of North River from Shijiao to Lubao, the shunt volume change before and after the riverbed entrenchment was calculated, under the condition of a typical year upstream flow. The results show that the shunt volume was considerably reduced because of the riverbed entrenchment and tile Lubao sluice construction. For upstream flow of a typical year （P=97%） , compared to the past condition （ i. e. without Lubao sluice and before the riverbed entrenchment） , the shunt volume reduces by 96. 5% under the present condition （i. e. with Lubao sluice of 2007 and after the riverbed entrenchment）.
