几百万年来奔流不息的黄河,有许多令人回味的趣事,下面例举二则。黄河揭底满河开花生活在龙门到潼关段黄河之滨的人们,每隔七、八年就能领略一次惊心动魄的景象:天降暴雨,河道水涨流急,只见河面竖起数米厚的泥皮墙,接着被滚滚洪水吞没卷走;百里河面泥皮此起彼伏,洪水浪头时高时低,看去满河象开花,听去水声震耳。数小时之后,洪水冲出一条几米深的河床,浩浩奔向大海。黄河这种自然奇观是一种“揭底”现象,这种现象古已有之,解放后已发生过五次。据说,黄河“揭底”前河道中出现一片片因泥沙淤积而形成的沙洲,河床比以往抬高,河道散乱。每过七、八年,如果天降暴雨,出现每秒800立方米以上的大洪水,数小时后揭底景象随之就会发生。据国内一些科学家说,“揭底”现象至今还是一个未解之谜。上游断流河底朝天 1986年10月15日,黄河上游的龙羊峡水电站大坝下闸蓄水,使黄河由龙羊峡至刘家峡一段240多公里河道主流断了水,黄河上游河床奇观因此展露出来。在干涸的河床上走,只见两岸高达200—300米的石崖峭壁,象刀劈斧削一样垂直笔立。奇形怪状的巨石静静地躺在河底,一块挤着一
There are many entertaining anecdotes of the Yellow River, which has been flowing for millions of years. Here are two examples. The Yellow River reveals Manchu flowering life Longmen to the Tongguan section of the Yellow River coast of people, every seven or eight years will be able to enjoy a thrilling scene: heavy rains, the river rose in rapidity, saw the river erected a few meters thick Mud wall, and then swallowed by the billowing swept away; Baili river mud one after another, when the flood waves low, looked like a river full of flowers, listening to the sound of water. A few hours later, the flood washed out of a few meters deep river, vast toward the sea. This natural wonders of the Yellow River is a kind of “revealing the end,” a phenomenon that has existed for a long time and has occurred five times since the liberation. It is said that the Yellow River “before the end ” appeared in a piece of river sand silt formed by sedimentation, the riverbed elevation than in the past, the river scattered. Every seven or eight years, if it rains, there will be a flood of 800 cubic meters per second or more, and a few hours later it will happen. According to some scientists in China, the phenomenon of “revealing” is still an unsolved mystery. Upper reaches of the river flow overturned on October 15, 1986, the upper reaches of the Yellow River Dam Longyangxia dam impounded water, so that the Yellow River from Longyangxia to Liujiaxia a section of more than 240 km of the mainstream of the river off the water, so the upper reaches of the Yellow River wonder spectacle Revealed. Walking in the dry riverbed, saw the rock cliffs of 200-300 meters on both sides of the strait, vertical pen stand like a knife cut ax. Bizarre boulders lay quietly on the bottom of the river, one crowded with one
