海河干流长成密码
发布时间：2018-11-03 20:31
【摘要】：正海河干流从南北运河交汇处的三岔河口(金钢桥)到大沽海口,全长只有72公里,不但是我国大江大河中干流最短的,而且也是最年轻的。一万年前,今河北平原上海河水系诸河,在黄河的率领下,汹涌澎湃地冲入了全新世。全新世的海河自然史,差不多是与黄河的自然史交融在一起的。—万年前,今天海河所属的众多支流,或直接注入渤海,或是黄河的支流。在大气圈-岩石圈-水圈的交互作用下,在人类的强烈参与下,整个黄河系统进入了一个躁动、创造时期,黄河在下游不断上演着决溢
[Abstract]:The main stream of the Zhenghai River is only 72 kilometers long from Sancha River entrance (Jingang Bridge) to Dagu Haikou, which is not only the shortest but also the youngest of the great rivers in China. Ten thousand years ago, the rivers of the Shanghai River in Hebei Plain, led by the Yellow River, stormed into the Holocene. The natural history of the Haihe River in the Holocene was almost intermingled with the natural history of the Yellow River.-Ten thousand years ago, many of the tributaries to which the Haihe belongs today were directly injected into the Bohai Sea or the tributaries of the Yellow River. Under the interaction of atmosphere, lithosphere and hydrosphere, and with the strong participation of human beings, the whole Yellow River system entered a period of restlessness and creation, and the Yellow River continued to overflow in the lower reaches.
