| 摘 要： | 北港是长江河口的重要组成部分,近几十年来对北港的研究甚少。本文在前人研究的基础上,结合水文泥沙和地形资料,着重对北港中段(堡镇-团结沙水闸)近三十年来的河势变化进行分析。20世纪70年代以来,北港的河势变化经历了三个时期:(1)河势动荡时期(1972-1985年);(2)河势调整时期(1985-1996年);(3)河势相对稳定时期(1996年至今)。北港上口通道的变化是制约北港河势变化的主要原因。

| Abstract: | The North Channel is an important component part in the channel system of the Changjiang Estuary.However,studies on it is hard to find in the past few decades.On the basis of previous researches on the North Channel,this paper emphatically analyses channel processes of the North Channel(from Buzhen Port to Tuanjiesha Sluice) in the past thirty years with the data of hydrodynamics and bathymetric maps from 1972 to 2002.There are three periods in the processes of the North Channel since the 1970s:(1)the instability(1972-1985);(2)the readjustment(1985-1996);(3)the relative stability(1996-present).The chief cause of evolution of the North Channel is the regim change of the bifurcation mouth between the South and North Channel. |
