The soil improvement effect of afforestation in grassland ——— take Gegentala grassland as example
As an important terrestrial ecosystem, grassland plays an important role in maintaining soil functions, nutrient cycling, and maintaining biological diversity.However, due to over‐use and over‐grazing, some grasslands have degenerated and become desertified, As a result, the production capability is often reduced year by year, and the development of animal husbandry has been hindered seriously.Afforestation in grassland can improve the ecological environment, mitigate natural disasters and improve yield and quality (Jianquan Yu,2000).Therefore, it is necessary to study the effect of afforestation on soil improvement in grasslands to better understand its role on soil and water conservation.
