Abstract:

In this paper, the characteristics of the vertical distribution of the forest vegetation on Emei Mountain was discussed. Using the methods of quantitative classification and the analysis combining the ecological physiognomy and floristic composition, according to the altitudinal distribution of plant communities, four vertical zones of forest vegetation may be discerned:

1. The evergreen broad-leaf forest zone below 1900m;

2. The evergreen and deciduous broad-leaf mixed forest zone 1500—2000m;

3. The needle-leaf and broad-leaf mixed forest zone 2000—2500m;

4. The cold-temperate coniferous forest zone 2500—3099m.
