摘　　要：杭州湾北岸经历了先侵蚀后淤涨的历史过程。近年来由于南汇边滩大规模促淤圈围工程及长江来沙量减少,造成冲刷带由东向西移动。经分析东部南汇段2003年以来处于冲淤平衡阶段,奉贤段总体上处于冲刷状态,顶冲点移至三团港附近,金山段处于相对稳定状态。The north of Hangzhou Bay has experienced the processes from retreat to siltation. In recent years, the erosion zone has moved from the east to the west due to both the reclamation works on large scales along the Nanhui tidal flat and decreasing of sediment fluxes from the Yangtze River. The Nanhui section in the east part of Hangzhou Bay has been in balance between erosion and sihation since 2003, and the Fengxian section has experienced erosion on the whole, with the erosion zone shifting to a location near Santuangang, and the Jinshan section in the west part is now in relative steady state.
