This paper analyzes the causes and countermeasures of serious soil erosion in barren hills of the Loess Plateau from both natural and human aspects.

There are many valleys and valleys in the Loess Plateau, and the surface fluctuates greatly, so it is easy to be eroded by running water. In temperate monsoon climate zone, there are many heavy rains in summer, which seriously damage the surface; Loess has fine particles, loose soil and strong collapsibility, and is easy to be lost with water. Poor vegetation and poor soil consolidation ability.

(2) Human causes

Human activities destroy vegetation and stable terrain, and aggravate soil erosion.

(3) Solution: Adjust the agricultural structure, and on the basis of protecting the existing vegetation, return farmland to forest and grassland; Develop diversified agriculture and other industries to increase farmers' income; Building soil and water conservation forest on the Loess Plateau; Develop biogas, etc. Solve the living energy problem of local farmers; Build terraces and develop planting in areas with small slopes; Protect vegetation in mining and engineering construction, and protect waste residue and soil in mining areas and engineering construction areas; Control population growth and conduct ecological migration if necessary; National policies should provide financial and technical support.
