3 Terms and definitions

The following terms and definitions apply to this document.

Natural grasslands with sandy surface environments in different climatic zones are affected by adverse natural factors such as wind erosion, water erosion, drought, rodent and insect pests, as well as overgrazing and excessive exploitation.

The impact of human economic activities such as excessive digging and reclamation has caused grasslands to suffer varying degrees of damage, soil erosion, topsoil desertification, and reduced grassland productivity.

etc. desertification process.

Sandified grassland

Natural grasslands with sandy soil are affected by natural factors such as wind erosion, water erosion, drought, rodent and insect pests, or by human factors such as overgrazing, over-mining, and reclamation.

The influence of mobile factors is manifested as vegetation degradation, the appearance of spotted quicksand on the surface, and in severe cases, the formation of grasslands with mobile, semi-mobile sand or wind erosion pits.
