What is the function of vegetation?

Vegetation has a good purification effect on the earth's atmosphere, which can make the air better and reduce the dust in the air. Most plants have some fine hairs, mucus, grease and other items growing on the leaf epidermis. These things can adsorb dust and harmful substances in the atmosphere, purify toxic gases in the atmosphere, and have the functions of purifying the air and regulating the climate.

2. Protect soil and water:

Vegetation has a strong role in soil and water conservation, and the plant community with a large coverage area covers the sediment surface, which reduces the erosion of the surface by rainwater and reduces the soil erosion on the surface. The roots of plants can also protect sloping fields and conserve water sources, and the leaves of plants can also perform transpiration, which can reduce land drought and prevent land desertification.

Vegetation refers to the plant community covering a certain area of the earth's surface, which is the general name of the plant community covering the earth's surface. It is a term of botany, ecology, agronomy or earth science, including many plants. Vegetation will form different types in different climatic conditions, and light, temperature and rainfall will affect the growth and distribution of plants and form different plant communities.
