About coniferous forest and broad-leaved forest ~

If a mountain high enough is located in the equatorial region with abundant water resources, a complete natural landscape belt spectrum similar to that arranged from the equator to the poles will appear on this mountain. On vegetation, tropical rain forest, evergreen broad-leaved forest, evergreen broad-leaved and deciduous broad-leaved mixed forest, deciduous broad-leaved mixed forest, coniferous forest, alpine shrub, alpine meadow and alpine tundra will appear in turn.

Evergreen broad-leaved forest is mainly distributed in the subtropical humid climate zone in the eastern part of the mainland, which is usually called subtropical evergreen broad-leaved forest. Evergreen broad-leaved forest and tropical rain forest are both dense forests composed of evergreen broad-leaved trees, but evergreen broad-leaved forest is very different from tropical rain forest, and some characteristics are more similar to summer broad-leaved forest. The typical evergreen broad-leaved forest is much simpler in structure than the tropical rain forest, with shorter community height and neater crown. Usually, there are only two layers of trees, and there are few interlayer plants such as vines, strangled plants and epiphytes, and there are few typical phenomena of tropical rain forest such as old stem flowers and roots. Although evergreen broad-leaved forest is evergreen all year round, it is different from tropical rain forest and has certain seasonal changes, similar to summer broad-leaved forest. The flowering period of evergreen broad-leaved forest is mostly concentrated in late spring and early summer, and the fruit is mostly in autumn. Some animals in evergreen broad-leaved forest hibernate, especially amphibians and reptiles. There are fewer species in evergreen broad-leaved forest than in tropical rain forest, but the dominant species are much more obvious. Fagaceae, Lauraceae, Theaceae, Magnoliaceae and Hamamelidaceae are the main tree species in evergreen broad-leaved forest. Trees in a typical evergreen broad-leaved forest usually have the characteristics of Lauraceae, with tough leaves and bright surfaces, and the leaves tend to face the sun. Therefore, the evergreen broad-leaved forest is also called the forest with bright leaves.
