Characteristic Analysis of the Evergreen Broad-Leaved Forest on the North Slope of Huangshan Mountain

Cai Fei and Qian Xiao-hu   

Abstract: he evergreen broad-leaved forest is widely distributed on the north slope of Mt. Huangshan. Through extensive investigation and analysis of the characteristics,the following conclusions can be achieved. The floristic composition consists of 81 families, 150 genera and 204 species, in which the subtropical elements are of high percentage. The physiognomy of the communities was analyzed on the basis of life forms of plants and their leaf characteristics. In the community structure,there is a distinct stratification and a complex synusiae. For horizonal structure,the pattern of dominant populations follows contagious distribution. Species diversity indexes are about 1. 159–3. 680. Ecological dominance indexes are about 0. 140–0. 481 Community evenness indexes are about 0. 507–0. 920. There are eight formations and twelve associations. Castanopsis sclerophylla formation,C, eyrei formation ,Cyclobalanopsis glauca formation and C. gracilis formation are stable phytocoenosium types. C. rnyrsinaefolia formation: and Lithocarpus henryi formation are unstable phytocoenosium types. They will be replaced by C. glauca formaton.

Key words: North slop of Mt. Huangshan, Evergreen broad-leaved forest
