黄河流域面积75万多平方公里,其中水土流失面积43万平方公里,是世界闻名的多泥沙河流,平均每年输入渤海泥沙12亿吨,下游每年平均淤积4亿吨。黄河百害的主要症结是泥沙多,泥沙就来自黄土高原的水土流失。多年的经验说明,水土保持是发展黄土高原农林牧业生产的根本措施,也是“根治黄河水害,开发黄河水利”的基础。
The Yellow River Basin covers an area of more than 750,000 square kilometers, of which 430,000 square kilometers of soil erosion area is the world famous multi-silt rivers, the average annual input into the Bohai Sea sediment 1.2 billion tons, an average of 400 million tons silt downstream. The main crux of the Hundred Hundreds of the Yellow River is sediment and sediment from the soil and water loss in the Loess Plateau. Years of experience shows that soil and water conservation is the fundamental measure for the development of agriculture, forestry, animal husbandry and production in the Loess Plateau and also the basis for “rooting the Yellow River water damage and developing the Yellow River water conservancy.”
