| 摘 要： | 根据大量高分辨率单道地震和浅地层剖面资料,在长江口外内陆架发现了大量埋藏古河谷,根据埋藏古河谷断面的形态参数,加以公式计算得到古河谷其它特征参数,使用宽深比-曲率和比降-河宽2种河型判别方法分析判别了该古河谷的河型,认为比降-河宽法在该区域河型判别中具有较好的效果,并判别出晚更新世末次盛冰期和冰消期古长江在研究区域以辫状型河道为主.

| Abstract: | A lot of high resolution single channel seismic data and sub-bottom profile data show that there are many buried channels in the inner continental shelf out of Yangtze River in the East China Sea.Some characteristic parameters of the profiles were figured out through some formulae based on the configuration parameters of the buried ancient profiles.Two channel pattern discrimination methods of the width-depth ratio curvature and the slope-width were used to distinguish the ancient channels.The analyzed resu... |
