The benefits of forests

1. Forests can also conserve water and soil, which plays a very important role in flood control and drought relief. Forests can also reduce noise and prevent dust, sandstorms and so on.

There are many green plants in the forest, so the forest can purify the air, absorb carbon dioxide and produce oxygen.

There are many animals in the forest, and these animals regard the forest as their habitat for reproduction and survival.

Evolutionary history

The formation and development of modern forests have experienced a long evolutionary process, which is generally divided into three stages:

1. Pteridophyte ancient gymnosperm stage

During the Carboniferous and Permian in the Late Paleozoic, large areas of coastal and inland swamp forests were composed of ferns, shrubs and herbs. Among them, lepidoptera and seal wood are important coal-making plants in Carboniferous, with a height of 20 ~ 40m and a diameter of1~ 3m. Tree ferns left in the tropics.

2. gymnosperms stage

The late Triassic, Jurassic and Cretaceous of Mesozoic are the heyday of gymnosperms. Cycas, Cycas Ben, Ginkgo biloba and conifers form a large area of gymnosperms and coniferous forests on the earth.

3. Angiosperm stage

In the late Cretaceous of Mesozoic and Tertiary of Cenozoic, angiosperm trees, shrubs and herbs appeared in large numbers one after another, all over the earth, forming various types of forests, which is the most dominant and stable plant community.
