Abstract

A method of conserving the vegetation at Mt. Chonggye was established to persue a practical management of the natural ecosystem by the vegetative composition analysis. As a result, the vegetation of surveyed areas was classified into two communities and four subcommunities in Mt. Chonggye. Potentilla fragarioides var. major community, known as the roadside plant community, distributed near trails under heavy human impacts. Potentilla fragarioides var. major community included two subcommunities : Digitaria sanguinalis-Ambrosia artemisiifolia var. elatior subcommunity and Rhus chinensis subcommunities. In these communiyies, there were many naturalized plant species such as Aster pilosus and Artemisia princeps var. orientalis, known as heliophilous plant. Results indicated that the vegetation had been affected by intensive human activities. It is necessary to control the naturalized plant species such as Aster pilosus for conservation of the ecosystem and nature in this area. Quercus mongolica community, a common coppice woodland in central Korea, was mostly distributed around mountain tops and ridges above 529 m altitute. In the valley where the forests well conserved, the Quercus mongolica community contained the Syneilesis aconitifolia-Hemerocallis lilioasphodelus subcommunity. On the other hand, Potentilla dickinsii subcommunity was dominated in dry rocky ridge areas. In these areas, however, the vegetation and forest soil was not properly managed for conservation.
