黄河涨上天怎么办？黄河流经黄土高原时，每年携带约１６亿吨的泥沙进入下游。如果将这些泥沙堆成宽高各１米的沙堆，其长可以绕地球２７圈由于下游地势平缓且沙多水少，泥沙难以全部排入海洋，其中约有４亿吨留在下游河床上，使黄河河床以每年平均１０厘米的速度抬升。目前下? How does the Yellow River go up to heaven? When Yellow River flows through the Loess Plateau, it carries about 1.6 billion tons of sediment every year to enter the downstream. If these sediments are piled into one-meter-wide sand piles, their length can be 27 laps around the earth. Because the downstream terrain is flat and there is less sand and more water, it is difficult to discharge all of the sediment into the sea, of which about 400 million tons are left downstream. On the riverbed, the riverbed of the Yellow River is lifted at an average speed of 10cm per year. Currently down?
