Abstract

Community types and population structures of the Pinus densiflora forest established the Bulyeongsa valley in Uljin Gun, were studied from vegetation ecological approaches. For the community types, four communities and four subcommunities were classified and six vegetation units grouped. In the mportance value(I.V.) analysis of the major component species, Pinus densiflora showed most highly in the tree layer and Quercus spp.(Quercus mongolica and Quercus variabilis) below the subtree layer. In the results of distribution of diameter classes of the major populations, there were a little differences by a micro topography, but it was considered that Pinus densiflora forest of this area changed potentially as Quercus spp. forests due to a rapid success of Quercus spp below the lower layer. For analyzing of the spatial structures for the most representative Pinus densiflora populations of this area, the distribution of individual trees, crown projection and stand profile diagrammed and growth curves showed in the four sites. The annual average diameter growth of Pinus densiflora of this area is from 1.22 to 3.26㎜.
