我国唐代诗人李白曾写道：“黄河之水天上来，奔流到海不复回”。 Li Bai, a poet of Tang Dynasty in China, once wrote, "the water of the Yellow River rises in the sky and flows to the sea without returning.". 从地图上看，黄河干流像一个巨大的“几”字。 From the map, the main stream of the Yellow River looks like a huge "several" character. 有人说：黄河是中华民族的母亲河，它为中华文明作出了巨大的贡献。也有人说：黄河是一条害河，它在历史上曾多次决口泛滥，给黄河流域的人民带来了深重的灾难。那么，我们将怎样看待黄河的呢。 It is said that the Yellow River is the mother river of the Chinese nation, which has made great contributions to Chinese civilization. It is also said that the Yellow River is a harmful river. It has burst and overflowed many times in history, which has brought serious disasters to the people in the Yellow River Basin. So, what do we think of the Yellow River. 黄河流经地区，一般降水不足。黄河水，使一块块干涸的土地展现了生机。 The Yellow River flows through the area, and the precipitation is generally insufficient. The Yellow River water has brought vitality to the dry land. 黄河的下游早有“地上河”之称！那“地上河”又是怎样形成的呢原来，黄河中游流经支离破碎，土层疏松的黄土高原，支流也比较多。由于黄土高原植被遭到破坏，一遇暴雨大量的泥沙与雨水一起，汇入黄河，使黄河成为全世界含沙量最多的河流。据观测，黄河仍以平均每年10厘米的速度向上升高。黄河之害，在于下游决口改道。因为大量泥沙入河并在下游河道沉积。黄河泥沙百分之九十来自中游，因此，加强中游黄土高原地区的水土保持是治黄的根本。 |
