Abstract
This study analyzed the actual vegetation and vegetation structure around the trails with the aim of restoring vegetation and continuous monitoring of the section between the National Astronomy Observatory and Birobong in Sobaeksan National Park. The actual vegetation was classified into 18 types, of which the largest were Quercus mongolica communities occupying the dimension of $225,337m^2$, Rhododendron schlippcubachii communities distributed around the trails on the ridge were covering 14.59%, and deciduous broadleaf forests were covering 11.06%. of the surveyed areas, respectively. In consideration of the actual vegetation, a total of 23 belt-transects were set up; 9 in Quercus mongolica communities, 3 in broadleaf deciduous forests, 2 in Taxus cuspidata communities, and 9 in damage restoration areas to take a closer look at the species diversity, species number, and individual number by community. The survey results are as follows: 9 belt-transects in Quercus mongolica communities showed their species diversity was $0.4290{\sim}1.0496$ with $7{\sim}22$ species and $115{\sim}481$ individuals. 3 belt-transects in broadleaf deciduous communities showed that species diversity was $0.6712{\sim}1.0096$ with $14{\sim}17$ species and $158{\sim}453$ individuals. 2 belt-transects in Taxus cuspidata communities showed that species diversity was $0.5413{\sim}0.9923$ with $14{\sim}15$ species and $223{\sim}406$ individuals. 8 belt-transects showed that species diversity was $0.1899{\sim}0.9217$ with $3{\sim}23$ species and $105{\sim}485$ individuals.
본 연구는 소백산국립공원 천문대${\sim}$비로봉 구간의 식생복원 및 지속적 모니터링을 위해 구간내 탐방로 주변 현존식생과 식생구조를 분석하였다. 현존식생은 총 18개 유형으로 구분되었으며 이중 신갈나무군집이 $225,337m^2$로 가장 넓은 면적이었고 능선부 탐방로 주변을 중심으로 분포하는 철쭉꽃은 14.59%, 낙엽활엽수군집은 11.06%이었다. 현존식생을 고려하여 총 23개의 Belt-transect(BT)를 설치하였으며 신갈나무군집내에 9개소, 낙엽활엽수군집내에 3개소, 주목 군집내에 2개소, 훼손복원지내에 9개소를 설정하였다. 신갈나무군집내에 설정한 9개소는 종다양도 $0.4290{\sim}1.0496$, 종수 $7{\sim}22$종, 개체수$115{\sim}481$개체이었고 낙엽활엽수군집내에 설정한 3개 BT의 경우 종다양도 $0.6712{\sim}1.0096$ 종수 $14{\sim}17$종, 개체수 $158{\sim}453$개체이었다. 주목군집내에 설정한 2개 BT는 종다양도 $0.5413{\sim}0.9923$, 종수 $14{\sim}15$종, 개체수 $223{\sim}406$개체이었다. 훼손복원지내에 설정한 9개 BT는 종다양도 $0.1899{\sim}0.9217$, 종수 $3{\sim}23$종, 개체수 $105{\sim}485$개체이었다.
