据《科技日报》报道,黄河含沙量惊人,平均每立方米河水含沙38公斤,洪水期可高达650公斤。黄河每年从中上游带到下游的泥沙总量平均为16亿吨,其中有12亿吨泥沙填海造陆,截止1985年底,黄河河口平均每年造陆27平方公里,致使海岸线每年向海域平均推移300米,而河口一带岸线向海域年均推移390米,
According to “Science and Technology Daily” reported that the astonishing amount of sediment in the Yellow River, an average of 38 kilograms per cubic meter of river water, floods up to 650 kilograms. The annual total amount of sediment carried by the Yellow River from the upper reaches to the lower reaches is 1.6 billion tons on average, of which 1.2 billion tons of sediment are reclaimed for land reclamation. By the end of 1985, the average annual land occupation of the Yellow River estuary was 27 km 2, resulting in an average annual shift of coastline to the sea level 300 meters, while the estuary along the coastline to the sea with an average annual change of 390 meters,
