  含沙置最多的河流中国第二大河-黄河,是世界上含沙量最多的河流。平 均数值达37公斤/立方米,下游陕县站多年平均输沙量为16亿 吨(1933年曾达39.1亿吨),均居世界首位。

  Sediment set up river Second River - China the Yellow River, is the world's largest river sediment. The average numerical value up to 37 kg / m3, the lower reaches of Shanxian station long-term average sediment transport capacity of 1600000000 tons(in 1933 reached 39.1 tonnes), ranking first in the world.

  古籍中早有“黄水 一石,含沙六斗”、〃黄河斗水,泥居其七”的记载。黄河发源于青 海省巴颜喀拉山脉,自西向东流程5,464公里,在山东省北部入 激海。泥沙主要来自中游的黄土髙原,其中内蒙古自治区托克 托县河口镇至龙门段占全河来沙量的56%,龙门至潼关段占全河来沙置的34 %。

  In the ancient books had "yellow stone, sand six bucket", "the Yellow River bucketwater, mud in the seven" records. The source of the Yellow River Province, Yu Qingsea Bayan Har mountains, 5464 km from west to east flow, in the northern part of Shandong province into induced sea. Sediment mainly comes from the middle reaches of the loess high raw, where the town to Longmen estuary of the Inner Mongolia Autonomous Region river sediment of Togtoh County accounted for 56%, Longmen to Tongguan section of the river sediment accounted for 34%.

  进入下游的16亿吨泥沙,约有四分之一淤积在山东利津以上河道,使黄河成为地上河• 一半淤积在河口三角洲及滨海地区,其余输往深海。近年经过治理,输沙量已减 少。北美洲的科罗拉多河,含沙量27.5公斤/立方米,仅次于 黄河,但因流量小,年输沙量仅1.35亿吨。

  16 tonnes of sediment into the downstream, about 1/4 of deposits in Shandong Lijinabove the river, make the Yellow River become the river on the ground - half ofsiltation in the estuary Delta and coastal area, the other transported to the deep sea.In recent years, through the management, sediment load has been reduced. North America Colorado River, sediment yield of 27.5 kg / m3, second only to the Yellow River, but due to the flow of small, the annual sediment yield only 1.35 tons.

  世界大河中,年输 沙量仅次于黄河的是南亚的恒河,为14.5亿吨。但因其流量丰 富,含沙量仅合3.9公斤/立方米。世界含沙量最多的河The great rivers of the world, the annual sediment discharge after the Yellow River isSouth Ganges RIver, 14.5 tons. But because of its rich sediment flow, only 3.9 kg / m3. The world's largest sediment River
