THE STUDY ON THE VEGETATION OF THE TIANTANGZHAI MOUNTAINS OF THE DABIE MOUNTAINS, ANHUI PROVINCE

The vegetation types and vertical distribution are studied by this paper in the Tiantangzhai Mountains of the Dabie Mountains. There are coniferous forest, broad-leaved forest, scrubs, meadow, marsh and so on Form. Pinus taiwanensis appears about 800 meters above the sea level and Form. P. massoniana below it. Through investigation and analysis, it is firmly believed that the basic vegetation is subtropic evergreen broad-leaved forest rather than evergreen and deciduous broad-leaved mixed forest in here. The vegetation types are enriched by the find and study of Euptelea pleiospermum—Rhododendron anwheiense+Orixa japonica—Liriope platyphylla+Elatostema stewardii association in Anhui Province. Quercus stewardii is the coppice making a feature of many branches and low stem, and that is rather the ecophine of the poor soil, strong wind, low temperature and short growth period than genetic factor.
