【Abstract】 After the vegetation restoration and reconstruction of natural ecosystem or forest,the rainfall that holds back will be higher,and the water conservation of the ecosystem also will be intensified with the litter fail increases.Physical and chemical properties of soil will be better after vegetation restoration and reconstruction.At the same time,the water infiltration rate and the water-holding amount of soil will increase,and the surface runoff will decrease.更多还原
