黄河,是我们中华民族的摇篮。同时,它还以其丰富的泥沙在历史上写下了不朽的一页。首先,肥沃坦荡的华北平原就是黄河的伟大杰作。几千年来,黄河以其巨大的输沙能力,不断地进行着填海造陆的过程。距今约6000年以前,海平面开始稳定在与现在大体一致的位置上,渤海岸线大致在昌黎、文安、任丘、献县、德州、济南一线、(见图)。源于大陆的黄河及其他大小河流带来的大量泥沙输入海中,华北平原陆地方得以向外伸张,海岸向东推移。大约到十八世纪后期,华北平原大致已具现在的规模。现在的黄河三角洲,是1855年铜瓦厢决口夺大清河故道入海以后淤积而成的。经130
The Yellow River is the cradle of our Chinese nation. At the same time, it has historically written a monumental page with its rich sediment. First of all, the fertile and magnificent North China Plain is the great masterpiece of the Yellow River. For thousands of years, the Yellow River has continuously carried out the process of reclamation and land reclamation with its huge sediment transport capacity. About 6,000 years ago, the sea level began to stabilize at roughly the same level as today. The coastline of the Bohai Sea is roughly on the first line of Changli, Wen’an, Renqiu, Xianxian, Dezhou and Jinan (see photo). Large amounts of sediment from the Yellow River and other rivers originating from the mainland were input into the sea. The lands on the North China Plain were extended outward and the coast moved eastward. About the late eighteenth century, the North China Plain has roughly the present size. Now the Yellow River Delta is the copper wagons in 1855 after the battle to seize the Daqinghe old course silting up. After 130
