| 摘 要： | 应用高分辨率地球物理方法揭示舟山群岛和长江口邻近海域埋藏大量古河道。对埋藏古河道断面特征参数进行统计分析,利用河流计算公式得到埋藏古河道相关水文环境参数值。然后应用最新河型判别方法,分析判别晚更新世末次盛冰期和冰消期研究区埋藏古河道的河流类型为辫状型;并分析得到研究区古河道的宽深比(F=22.22)、悬移质含量(M=10.10%)、河道弯曲率(P=1.52)、河曲波长(L=1 647 m)等古水文泥沙环境参数分类指标。

| Abstract: | Many buried river channels were revealed by applying high-resolution geophysical detection methods in the area near Zhoushan Islands and Yangtze River estuary.The characteristic parameters of the buried channel profiles were counted and analyzed.Some characteristic parameters of hydrological environment of the profiles were figured out by using some river formulae.The river patterns of the study area were analyzed by the latest channel pattern discrimination in the last glacial maximum and deglaciation of t... |
