우리나라 남부권역에 분포하는 곰솔 임분의 식생, 생장, 형질을 권역 및 건전도에 따라 임분 특성을 분석하여 시업적 기초 자료를 제공하고자 본 연구를 수행하였다. 아교목층 이하에서는 교란임지가 건전임지 보다 많은 종이 출현 하였으며, 종 다양도 지수는 교목층을 제외한 모든 층위에서 건전임지(0.097 ∼1.520)와 교란임지(1.507∼1.669) 사이에는 유의적인 차이를 보였다. 교란임지와 지역별 유사도분석에서, 경상권과 전라권이 층위별로 0.280∼0.607, 제주권역은 0.189∼0.318로 지역 간 차이를 나타내었다. 연년생장량은 정상임분이(0.39∼0.48 ㎝/year) 교란임분(0.25∼0.37 ㎝/year)보다 높게 나타났으며, 생장율도 건전임지(7.74∼8.51%)와 교란임지(3.79∼5.52%)간에는 유의적 차이를 보였다. 임목 형질은 경상권과 전라권에서 B급 이하, 제주권은 B급 이상, 교란지에서는 C급의 비율이 상대적으로 높게 나타는 것으로 조사되었다. 따라서 곰솔 임분은 현재의 식생, 생장, 형질적 특성을 고려하여 차별화된 맞춤형 임분 관리가 필요할 것으로 판단되었다.
This study was performed to compare the healthy and disturbed areas of the black pine(Pinus thunbergii) forest located in regions nationwide, provide basic data according to forest composition characteristics and type, including vegetation structure, growth, and traits. The results of the analysis were as follows: As for vegetation composition, more species appeared in the disturbed forest than in the healthy forest for the shrub and ground layers, and results of species diversity index analysis showed higher species diversity in the disturbed forest (1.507∼1.669) than the healthy forest (0.097∼1.520). As for the similarity index between each region and the disturbed forest, results ranged from 0.280∼0.607 according to the level for the Gyeongsang and Jeolla regions, higher than the 0.189∼0.318 range for the Jeju region, and therefore it is thought that the Jeju region is less disturbed due to various reasons. As for CAI(Current Annual Increment), the Gyeongsang, Jeolla, and Jeju regions (0.39∼0.48cm/year) showed higher growth than the disturbed forest (0.25∼0.37cm/year), with a statistically significant difference between the healthy forest (7.74∼8.51%) and the disturbed forest (3.79∼5.52%). As for tree traits, the ratio of the B class was high in the Gyeongsang and Jeolla regions, and that of the A class was high in the Jeju region, whereas in the disturbed forest, the ratio of C was high, indicating relatively bad tree traits Therefore, it is judged that appropriate management methods need to be prepared for disturbed forest regions, where the differences in vegetation, growth and traits with healthy forest are growing larger, for sustained management in a tailored management system.
