“黄河涨上天怎么办?” 黄河因每年约有4亿吨泥沙淤积在下游河道,逐渐形成举世闻名的“地上悬河”。1952年毛泽东主席第一次出京巡视黄河,曾针对洪水和悬河问题发问:“黄河涨上天怎么办?”如今,通过广大治黄工作者长期不懈的努力,这个难 “How does the Yellow River go up to the sky?” The Yellow River is due to deposit about 400 million tons of silt in the downstream rivers each year, gradually forming the world-famous “overground suspension.” In 1952, Chairman Mao Zedong visited the Yellow River for the first time to visit the Yellow River. He once asked the question of floods and overhanging rivers: “How does the Yellow River go up to heaven?” Nowadays, through the unremitting efforts of the vast number of Yellow River workers, this is difficult.
