소백산의 천연생 주목나무림 식생구조

Abstract

This study was carried out to investigate the structural characteristics of Taxus cuspidata communities in Mt. Soubaik. The vegetation was consisted of 14 species in the T1(tree) layer, 28 species in the T2(subtall tree) layer, 22 species in S(shrub) layer, and 61 species in the H(herb) layer. The dominant species of Mt. Soubaik was Taxus cuspidata in the T1 Layer, Acer tschonoskii var. rubripes in the T2 Layer, Weigela florida and Tripterygium regelii in the S Layer, and Pseudostellaria palibiniana in the H layer. DBH distribution of T1 Layer by Weibull Distribution estimated highly significant between Taxus cuspidata and other species(95% Confidence level). DBH distribution curve was skewed to the left. 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.
