黄河孕育了中华民族,它对世界文明作出过辉煌贡献。但是,长期以来,对土地资源的过度垦殖利用,使黄河中游的黄土高原植被破坏无遗。降水不能含蓄,雨季大量迳流挟带泥沙泻泄,河床不断淤积抬升,下游受洪水严重威胁,旱季则河流断流。这不仅是黄土高原地区贫穷落后的物质根源,也是下游人民生命财产、国土安全的不稳定因素,其危害程度为世界河流之冠。
The Yellow River gave birth to the Chinese nation and made brilliant contributions to world civilization. However, for a long time, the over-exploitation of land resources has destroyed the vegetation of the Loess Plateau in the middle reaches of the Yellow River. Precipitation can not be implied. During the rainy season, a large amount of stagnant water drained sediment and laxation. The riverbed is continuously silted and uplifted. The downstream area is seriously threatened by floods and the river is cut off during the dry season. This is not only a source of poverty and backwardness in the Loess Plateau, but also a destabilizing factor in the life and property of the downstream people and homeland security. The extent of the damage is the highest in the world.
