The phenomenon that forests can purify the air and regulate the climate is mainly manifested in the impact of organisms on the environment.

The environment will affect plants. Environmental factors such as light, temperature, rainfall and soil type will affect plants. For example, in tropical areas with strong light, high temperature and good moisture, the leaves of plants are large, while in cold high latitudes, the leaves of plants are small.

In the tropics, plants are evergreen, while in the temperate zone, most plants are deciduous; The influence of plants on the environment is that plants change the surrounding environment through their own actions. For example, in tropical and subtropical areas, plants grow rapidly, and the demand for minerals is relatively large. Therefore, plants secrete organic acids from roots to increase the supply of phosphorus and calcium, resulting in low soil pH and acidity.

On the contrary, in temperate regions, soil pH is neutral or alkaline. The soil organic matter content in forest is high, and it has strong affinity with water, which can absorb rainfall, reduce the formation of debris flow and improve the regional microclimate. Therefore, the forest can purify the air, adjust the climate phenomenon and the influence of plants on the environment.

The main components of climate are temperature and precipitation. The influence of forest on climate is mainly manifested in local microclimate: the existence of forest and transpiration can make local air more humid, increase air humidity, and the corresponding rainfall will also increase.
