Plant Community Structure ＆ Distribution Density of Pinus thunbergii-Pinus densiflora Forest in Kojedo District, Hallyo-Haesang National Park

한려해상국립공원 거제도지구 곰솔-소나무림의 식물군집구조와 분포밀도

Thirty-two plots have been set up and surveyed to investigate the plant community structure and distribution density of Pinus thunbergii-P. densiflora forest in Kojedo District, Hallyo-Haesang National Park. By DCA ordination technique P. thunbergii-P. densiflora forest was classified into P. thunbergii community, P. thunbergii-P. densiflora community, and P. densiflora community. The trend of plant community succession was invalid. The results of simple regression analysis between mean DBH(cm), mean distribution distance(m), and number of individual of P. thunbergii and P. densiflora were as follows: Distribution distance(m) = 0.094$\times$DBH(cm)-0.1248, Number of individual=1,820.1$\times$(cm)$DBH^{-1.6734}$ , Distribution distance(m)=6.6805$\times$Number of $individual^{-0.5425}$ .

한려해상국립공원내 거제도지구 곰솔-소나무림의 식물군집구조와 분포밀도를 규명하기 위해 32개 조사구(10m$\times$10m)를 설정하였다 DCA분석 결과 곰솔군집, 곰솔-소나무군집, 소나무군집으로 분리되었고, 각 군집의 천이경향은 불명확하였다. 조사구별 교목층의 곰솔과 소나무의 분포밀도 현황에 대해 단순회귀분석을 실시한 결과는 다음과 같았다. 분포거리 (m) = 0.094$\times$흉고직경 (cm)-0.1248, 개체수=1,820.1$\times$흉고직경 $(cm)<^{-1.6734}$ , 분포거리 (m) = 6.6805$\times$$개체수^{-0.5425}$
