덕유산의 천연생 주목나무림 식생구조

Abstract

This study was carried out to investigate the structural characteristics of Taxus cuspidata communities in Mt. DuckYoo. The vegetation was consisted of 20 species in the T1(tree) layer, 26 species in the T2(subtall tree)layer, 26species in S(shrub) layer, and 56 species in the H(herb) layer. The dominant species of Mt. Duckyoo was Taxus cuspidata in the T1 Layer, Acer tschonoskii var. rubripes in the T2 Layer, Tripterygium regelii and Acer tschonoskii var. rubripes in the S Layer and Sasa borealis in the H Layer. According to the diameter distribution of high ranking five species in T1, T2 layer at natural Taxus cuspidata communities, these forests may be gradually replaced by Quercus mongolica, Tripterygium regelii. The composition of biological type was Ph-D1-R5-e.
