Abstract

In this paper based on the investigative data in a sample area of 7 000 m²,analysis was made of species composition, community structure and life form spectrum of the mid-mountain humid evergreen broad-leaved forest (MHEBF) in southern part of Mt. Gaoligong. The results showed that (1) there were 315 species of vascular plants, which belonged to 88 families and 164 genera. The main families were Lauraceae, Ericaceae,Liliaceae and Fagaceae. The main genera were Lindera,Viburnum,Polygonum and Symplocos. (2) The community could be divided into different levels, epiphyte species and hemiepiphyte species were rich,which indicated the moist habitat. (3) The microphanerophytes and mesophanerophytes were the dominant life form, which revealed the characteristic of subtropical evergreen broad-leaved forest. Microphyll, single leaf, papery leaf, non-entire margin leaf and acuminate leaf were dominant leaf characteristics. Temicryptophyte occupied the highest ratio, therophyte and geophyte were less, which showed the typical subtropical mountain forest community characteristics in Yunnan Province.
