The role of forest water storage

Forests can conserve water and play an important role in the natural circulation of water. "Green mountains are always there, and green water is always flowing." Trees are always associated with water. Part of the precipitation rainwater is intercepted by the canopy, most of it falls into the litter under the tree and is stored in the loose and porous forest soil, some of it is absorbed by the roots of plants in the forest, and some of it returns to the atmosphere through evaporation. 1 hectare of forest can evaporate 8000 tons of water a year, which makes the air in the forest area moist, increases precipitation, and makes it warm in winter and cool in summer, thus playing a role in regulating climate.
