Fig. 4 Responds of tree species richness to environmental factors. The solid line shows the estimations of tree richness, and the dashed lines indicate 95% confidence interval.
This paper discusses species richness, evenness and species diversity of higher plants in deciduous broadleaved forests on the northern slope of Taibai Mountain.
In the process of secondary succession from conifer - broadleaf forest to broadleaf forest, species richness fluctuated remarkably.
