摘　　要：通过对长江口北支CY、XL1、XL2及表层沉积物的沉积特征分析,揭示长江口北支沉积沙体在垂直方向上沉积相序的演变规律,北支表层沉积特征及其分布规律,进而探讨长江口北支河道的演变趋势,为长江口北支的进一步开发整治提供科学依据。Through analyzing the sedimentary characteristics of sedimentation samples from core CY,XL1,XL2 and surface layer in the North Branch of the Yangtze River Estuary,the vertical sedimentation rules and the surface layer sedimentary characteristics in the North Branch is indicated.Meanwhile,the channel evolution processes of the North Branch are also investigated.The research results may provide a scientific reference to the development and regulation of the Yangtze River Estuary.
