Abstract

The characters of Chamaecyparis obtusa community extended around the Mt. Gyeryoung in Geoje-cik were investigated for several ecological parameters and the results can be summarized as fellows. Chamaecyparis obtusa is prevailing in the plantation area, whereas Pinus densiflora and Quercus mongolica are prevailing in its outskirts. Plant biomass and net production which estimated from degree of green naturality and Miami's model were much higher in the plantation than those of the natural forest. However, the mean species diversity of plantation was lower than that of natural populations. In stratification of investigated areas, overstory tree layer was dominant in the zone of plantation and dominant layers in the natural forest were understory tree layer, shrub, and herb.

본 조사 지역은 도심의 자연공간이 비록 인위적 조성이긴 하나 질적 및 양적으로 식생이 양호하게 잘 관리할 수 있음을 단적으로 보여 주었다. 식물상은 광범위한 조사 지역이 아님에도 불구하고 세 가지 특징이 있다. 첫째는 교과서적인 이차림에 의한 군락이 매우 양호하다는 점이다. 그러나 자연지역에서는 군락 형성이 미미했다. 둘째는 다양도는 자연집단에서는 높게 나타나고 조림지에서는 낮았다. 셋째, 자연 식생과 조림지의 종조성, 종다양도, 산림의 생산력에서 확연히 차이가 드러났다.
