| 摘 要： | 潍河-弥河三角洲是一个由多条河流共同塑造的三角洲。前三角洲黏土质粉砂是各河流共同贡献的结果;每条河口之外形成各自的三角洲前缘,主要由极细砂组成;河口间湾沉积物是两条相邻河流共同塑造的,主要为黏土质粉砂。由于河口位置的侧向摆动,三角洲前缘极细砂和河口间湾黏土质粉砂会交替出现。7000a B. P. 以来向海进积20~55km,在海岸附近三角州沉积物厚度超过20m。

| Abstract: | Weihe River-Mihe River Delta on the south coast of the Bohai Sea is contributed by the Jiaolai River,Weihe River,the Bailang River,the Mihe River and the Xiaoqing River,and the historical Jishui River existed in 11-1128 A.D.It is a river group delta.The coast line prograteded 20-55 km from 7000 yr B.P.to 1984.The delta thickness along the coast is over 20 m.The distances between two river mouths is approximately 20 km or less.The clayey silt of the prodelta is jointly constructed by all rivers,very fine san... |
