摘　　要：As the birthplace of the Chinese civilization, China’s Loess Plateau(CLP) has an area of ~640,000 km2 and supports a population of more than 100 million people. It has a history of intensive agriculture more than 1000 years. The loess deposit of CLP is the largest and deepest in the world. The abundance of silt grains in the loess deposit makes it relatively homogeneous, porous and prone to soil erosion.
