【摘要】：正海河干流從南北運河交匯處的三岔河口(金鋼橋)到大沽�？�,全長只有72公里,不但是我國大江大河中干流最短的,而且也是最年輕的。一萬年前,今河北平原上海河水系諸河,在黃河的率領下,洶涌澎湃地沖入了全新世。全新世的海河自然史,差不多是與黃河的自然史交融在一起的�！f年前,今天海河所屬的眾多支流,或直接注入渤海,或是黃河的支流。在大氣圈-巖石圈-水圈的交互作用下,在人類的強烈參與下,整個黃河系統(tǒng)進入了一個躁動、創(chuàng)造時期,黃河在下游不斷上演著決溢
[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.
