Abstract: Erosion brings a great damage to the agro-ecosystem and makes it unstable. Building terrace and covering land surface with trees and grasses can prevent water, soil and nutrient from erosion and leaching. And thus, the ecological equilibrium can be restored and the biomass can be increased in loess plateau.
