黄河发源于青藏高原巴颜喀拉山北麓的约古宗列盆地西南缘的雅拉达泽,曲折穿行于黄土高原、华北平原,最后在山东垦利县注入勃海。全长5464公里,有34条重要支流,流域面积75万平方公里,是中国第二大河。黄河以泥沙含量高而闻名于世。其含沙量居世界各大河之冠。据计算,黄河从中游带下的泥沙每年约有16亿吨之多,如果把这些泥沙堆成
The Yellow River originates from the Yaladzeze of the southwestern margin of the Paleozoic basin on the northern foot of the Bayan Kara Mountain in the Qinghai-Tibet Plateau. It twists and turns through the Loess Plateau and the North China Plain and finally into the Bohai Sea in Kenli County, Shandong Province. The total length of 5464 kilometers, 34 important tributaries, the basin area of 750,000 square kilometers, is China’s second largest river. The Yellow River is famous for its high sediment content. Its sediment ranks the highest in all major rivers in the world. According to calculation, the sediment transported by the Yellow River from the middle reaches is estimated at about 1.6 billion tons every year. If these sediments are made into
