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
The main stream of the Haihe River stretches from the Sancha River mouth (Jingang Bridge) to the Taku Haikou at the intersection of the North and South Canal. The total length of the Haihe River is only 72 kilometers. It is not only the shortest but also the youngest in China’s major rivers. Ten thousand years ago, all the rivers in Shanghai Creek in the Hebei Plain, under the leadership of the Yellow River, surged into the Holocene with surging surging waves. The Holocene’s natural history of the Hai River is almost integrated with the natural history of the Yellow River. - Years ago, many tributaries of the Hai River today, or directly into the Bohai Sea, or the tributaries of the Yellow River. Under the interaction of the atmosphere, the lithosphere and the hydrosphere, with the intense human participation, the entire Yellow River system entered a period of restlessness and creation. The Yellow River continued to show its influence in the downstream
