被尊为中华民族母亲河的黄河,得名于所夹带的泥沙。今日之黄河,已不是一个“黄”字了得,放眼望去,满河泥浆。黄河的含沙量是多少?河边的老百姓说,发洪水时一杯水能沉淀出半杯泥。科学的数字是:平均含沙量为每立方米37公斤,为世界之最。黄河每年夹带的泥沙有16亿吨。如果把这些泥沙筑成高宽各一米的长堤,可绕地球赤道30多周。
The Yellow River, which is regarded as the mother river of the Chinese nation, is named after the sediment it entrains. The Yellow River today is no longer a “yellow” word, looking ahead and full of mud. What is the amount of sediment in the Yellow River? People on the riverside say that a glass of water can precipitate half a cup of mud when it comes to floods. The scientific figure is: The average sediment concentration is 37 kilograms per cubic meter, which is the highest in the world. The annual sediment entrainment in the Yellow River is 1.6 billion tons. If we make these silt into a length and width of one meter long embankment, the equator can be more than 30 weeks around the Earth.
