What Is Vegetation?

Refers to the plant community covered by a certain area of the earth's surface. Divided by the type of plant community, it can be divided into meadow vegetation and forest vegetation. It is closely related to the natural environment elements such as climate, soil, terrain, animal kingdom and water conditions. From the global scope, it can be divided into two categories: marine vegetation and land vegetation. However, due to the large differences in the terrestrial environment, a variety of vegetation types have been formed, which can be divided into multi-level classification series such as vegetation types, flora and clumps. Can also be divided into natural vegetation and artificial vegetation. Artificial vegetation includes farmland, orchards, grasslands, artificial forests and urban green spaces. Natural vegetation includes primary vegetation and secondary vegetation. ^[1]

Environmental factors such as light, temperature, and rainfall affect the growth and distribution of plants, so different vegetation forms.

Fire may be the biggest factor affecting global vegetation distribution

In the past, temperature and rainfall in an area were considered to be key factors in determining which plants are grown in the area, and whether they are suitable for conversion to pasture, savanna, or forest. However, researchers from South Africa and the United Kingdom say that fires may be the biggest factor affecting the global vegetation distribution.

Pastures composed of Hi-Wen plants only appeared in tropical regions between 6 and 8 million years ago, but have since quickly spread to the world. The study found that the extension of the ranch was mainly affected by fires, although researchers do not yet know why there were so many fires at that time. Without fire, the area of forests will jump from 26% of the world's total vegetation to 56%; tropical pastures and savanna areas in South America and Africa will be reduced to half the current area; temperate pastures and The Mediterranean shrubland will be reduced by about 2/3, the study concluded.

There has been controversy over fire control in the United States. U.S. policy has banned any kind of tinder on public land. But in August 2000, the U.S. government revised related regulations because the government recognized that the nature of phosphorous fires plays an important role in maintaining certain ecosystems. Some biomes are intentionally planted in areas prone to fire.

"You can't think of fire as just a demon," said an ecologist at the University of Sheffield in the UK. "If we try to eliminate the fire, we will lose the ecosystem that has formed over millions of years. Because the natural ecosystem faces the test of fire, we have to actively face the principle of survival of the fittest, survival of the fittest," the research team concluded.
