黄河三角洲五号桩海区位于山东半岛北部现代黄河水下三角洲部分,为1972～1976年黄河自神仙沟、刁口河行水入海的区段,其位置在现代黄河入海口西北约40km处,距东营市约100km。该段岸线向海突出,0～15m等深线距密集,坡降较邻近区段最大,是目前黄河三角洲遭受强烈冲刷后退的区段。这种状态与东南部的现代黄河入海口处的迅速向海淤进,及西部的黄河故道以西套儿河口附近趋于平衡的特点,形成鲜明的对照。本文以1986～1987年实测资料为主,结
The Yellow River delta No. 5 pile sea area is located in the modern Yellow River submarine delta in the northern part of Shandong Peninsula. It is a section of the Yellow River from Shenxian Ditch and Diaokou River into the sea from 1972 to 1976, and its location is about 40km northwest of the mouth of the modern Yellow River. Dongying City about 100km. This section of shoreline protrudes to the sea, and the depth of 0 ~ 15m isotherm is intensive. The slope descent is the largest than that of the adjacent section. It is the section where the Yellow River Delta suffered a strong erosion and retreat. This state contrasts sharply with the rapid silting into the sea at the mouth of the modern Yellow River in the southeast and with the trend toward the balance near the Jiaolei estuary west of the old course of the Yellow River in the west. This article mainly from 1986 to 1987 measured data, knot
