Abstract
Mt. Kumjeong is located in south-eastern part of the Korean Peninsular($129^{\circ}$01' to $129^{\circ}$05' E, $35^{\circ}$03' to $35^{\circ}$17' N) and the altitude of the summit is 802 meter. In order to find out the vegetation units which made it possible to classify subtropical forest and south-temperate forest, Mt. Kumjeong (which is located in a border of between subtropical forest and south-temperate forest) was selected as a study area. The primary result of actual vegetation analysis in Mt. Kumjeong based upon the vegetation community analysis methods by the ZM-school, and the relationships between vegetation community and two parameters(altitude, topography) analyzed by using coincidence analysis method were summarized as followings. 1. Based upon analytic methods of the vegetation community by the ZM-schools, the primary analytic result of the analysis of vegetation community in Mt. Kumjeong was divided into 10 communities, 9 groups, 2 subgroups. 2. Eurya japonica group of Pinus densiflora community out of 16 vegetation units was thought as a indicator vegetation group which made it possible to border subtropical forest and south-temperate forest. 3. Natural regeneration of Stewartia koreana group was thought to be difficult because seedling and sapling was rarely showed, 4. In relationship between vegetation units and altitude, Carpinus tschonoskii community, Quercus variabilis community, Quercus serrata community, Wisteria floribunda community,. Eurya japonica group of Pinus densiflora community, Pinus thunbergii community mainly distributed below altitude 500 meter, and Quercus mongolica community, Typical group of Pinus densiflora community, Quercus dentata community, Carpinus coreana community, Quercus acutissima community mainly distributed above altitude 500 meter. 5. In relationship between vegetation units and topography, Carpinus tschonoskii community, Quercus variabilis community, Quercus serrata community, Wisteria floribunda community,. Eurya japonica group of Pinus densiflora community distributed below middle slope, Quercus mongolica community, Typical group of Pinus densifiora community, Quercus dentata community, Carpinus coreana community, Pinus thunbergii community Quercus acutissima communily clistributed above midclle slope.
난대림과 온대남부림의 경계를 구분할 수 있는 식생단위를 찾아내기 위하여 난대림과 온대남부림의 경계지역에 속한다고 추정되는 금정산(북위 $35^{\circ}$03' ~$35^{\circ}$17', 동경 $129^{\circ}$01'~$129^{\circ}$05')의 현존삼림식생을 중심으로 ZM 방식으로 식생분류를 하였고, 아울러 군락의 안정성을 구명하였던 바 다음과 같이 요약할 수 있었다. 1. 금정산 일대의 상림식생은 10개군락, 9개군, 2개소군으로 분류되었다. I. 개서어나무군락(群落) (Carpinus tschonoskii community) I-A. 노각나무군(群) (Stewartia koreana group) I-B. 쥐똥나무군(群) (Ligstrum obtusifolium group) I-C. 초피나무군(群) (Carex humilis group) II. 굴참나무군락(群落) (Quercus variabilis community) III. 졸참나무군락(群落) (Quercus serrata community) III-A. 거북꼬리군(群) (Boehmeria tricuspis group) III-B. 전형군(典型群)(Typical group) IV. 등나무군락(群落) (Wisteria floribunda community) V. 신갈나무군락(群落) (Quercus mongolica community) V-A. 조릿대群(Sasa borealis group) V-B. 그늘사초군(群) (Carex lanceolata group) V-B-1. 족도리소군(小群) (Asarum sieboldii subgroup) V-B-2. 해변싸리소군(小群) (Lespedeza ${\times}$ maritima subgroup) VI. 소나무군락(群落) (Pinus densiflora community) VI-A. 사스레피나무군(群) (Eurya japonica group) VI-B. 전형군 (Typical group) VII. 떡갈나무군락(群落) (Quercus dentata communty) VIII. 소사나무군락(群落) (Carpinus coreana community) IX. 해송군락(群落) (Pinus thunbergii communily) X. 상수리나무군락(群落) (Quercus acutissima community) 2. 16개 식생단위중 소나무군락의 사스레피나무군 (Eurya japonica group)이 난대림과 온대남부림을 경계하는 지표식생군인 것으로 사료되었다. 3. 노각나무군은 치묘와 치수가 나타나지 않는 점으로 미루어 상충임관아래에서는 천연갱신이 어려운 종으로 사료되었다. 4. 분류된 식생단위와 해발과의 관계에서 개서어나무군락 굴참나무군락 졸참나무군락 등나무군락 소나무군락의 사스레피나무군 해송군락은 주로 해발 500m이하에서, 신갈나무군락 소나무군락의 전형군 떡갈나무군락 소사나무군락 상수리나무군락은 주로 해발 500m 이상에 분포하고 있었다. 5. 식생단위와 지형과의 관계에서는 개서어나무군락 굴참나무군락 졸참나무군락 등나무군락 소나무군락의 사스레피나무군은 사면중부이하에서, 신갈나무군락 소나무군락의 전형군 떡갈나무군락 소사나무군락 해송군락, 상수리나무군락은 사면중부이상에 분포하고 있었다.
