tree layer

the vertical structure of each forest community were obvious and could be divided into tree layer , shrub layer , herbage layer and lianas.

Although our to feel pain, but she and shun the affection between the tree layer was so deeply.

The species richness and species diversity index of the tree layer and shrub layer were obviously bigger than those of the herb layer.

The utilization of tree layer is comparatively seldom and the utilization of liana, the bamboo and the aquatic plant is even rare.

Compared with species in tree layer, damages of woody seedlings, herbs or lianas growing under the canopies were largely reduced.

While in man-made forest belt, Moraceae, Lauraceae and Euphorbiaceae were the chief plants in the tree layer.

In shrub-tree stage , the species diversity in tree layer was lower than that of shrub layer .

The abundance index of the tree layer was higher than the shrub layer.
