摘　　要：江苏沿海地区入海河流众多,承担着沿海及腹地片区防洪排涝的重要任务.目前,闸下河道普遍发生淤积,且随着沿海滩涂围垦进程的加快,闸下港道淤积程度还在加剧.以王港为例,基于RS技术,提出了以纳潮汇水区历史外边线、河口现状主体汇水区边线,以及口外主槽演变外边线,作为确定河口滩面控制区域的参考.从海岸地貌学、河口海岸水动力学,以及泥沙运动学等角度,提出了沿海滩涂围垦的最大允许范围.There are a lot of sea entering channels in Jiangsu coastal zone, and they are charged with functions of flood control and drainage in seaside district and hinterland. At present, sedimentation of tidal channels downstream of sluices is universal and serious. What＇s more, with the rapid development of tidal fiat reclamation, sedimentation becomes more and more serious. As an example, based on coastal geomorphology, estuary ＆ coastal hydrodynamics and sediment hydraulics, Wanggang tidal channel is taken to study the influence of tidal flat reclamation on channel sedimentation downstream of tidal stuice in Jiangsu coastal zone was studied, and the allowable maximal tidal flat reclamation area is brought forward.
