지리산 웅석봉지역의 산림군집구조

To investigate the vegetation structure of mountain ridge from Bammeorijae to Woongseokbong, 25 plots(400m2) selected by random sampling method were surveyed. Three groups of Quercus mongolica - Pinus densiflora community, Q. dentata community and Q. mongolica - Q. dentata community were classified by cluster analysis. Q. dentata, Q. variabilis, Pinus densiflora, Acer pseudosieboldianum and Q. mongolica were found as mostly dominant woody plant species in the Woongseok-bong area. In the future, the importance percentage of Pinus densiflora might be eventually decreased, but those of Q. mongolica, Q. variabilis and Q. dendata might be gradually increased. There were strong positive correlations between Pinus densiflora, Zanthoxylum piperium and Lindera obtusiloba; Q. mongolica and Rhododendron mucronulatum; Styrax obassia and R. schlippenbachii; Fraxinus sieboldiana, Zanthoxylum piperium and Styrax obassia; Acer pseudosieboldianum and Fraxinus sieboldiana; Cornus controversa and Corylopsis coreana were relatively weak negative correlations between Q. dentata and Q. mongolica; Lindera erythrocarpa, Q. mongolica and Q. variabilis; Q. mongolica, Larix leptolepis and Q. variabilis; Symplocos chinensis for. pilosa and Rhododendron mucronulatum. Species diversity index(H') of investigated groups was ranged from 0.09832 to 1.1102.
