Abstract

This study was conducted to provide basic information for effective management strategies on nature trails in Mt. Jiri national park. Vegetation structure of nature trails in Yupyeong, Jungsanri, Hadong and Baekmudong districts was researched to accomplish the purpose of study. The tree and subtree layer consisted of 16 and 11 species for Yupyeong, 14 and 16 species for Jungsanri, 10 and 13 species for Hadong, and 19 and 10 species for Baekmudong district, respectively. The importance value of Quercu variabilis in the tree layer was highest for Yupyeong, Jungsanri and Baekmudong districts, and that of Pinus densiflora was highest for Hadong district. The herbaceous layer was composed of 70 species for Yupyeong, 53 species for Jungsanri, 65 species for Hadong, 57 species for Baekmudong districts, respectively. The value of species diversity ranged from 0.752 to 1.162, 0.957 to 1.085 and 1.283 to 1.506 at tree, subtree and shrub layer, respectively. Evenness ranged 0.752 to 0.983 at all layers for four nature trails in Mt. Jiri national park.

이 연구는 지리산국립공원 자연관찰로의 합리적 관리를 위한 기초정보를 제공할 목적으로 지리산국립공원내 유평, 중산리, 하동, 백무동 지역 자연관찰로 주변의 식생구조를 조사하였다. 교목층과 관목층은 각각 유평 지역 16종과 11종, 중산리 지역 14종과 16종, 하동 지역 10종과 13종 그리고 백무동 지역은 19종과 10종으로 이루어져 있다 유평, 중산리, 백무동 지역 자연관찰로의 교목층은 굴참나무의 중요치가 가장 높았으나 하동 지역은 소나무의 중요치가 가장 높은 것으로 조사되었다. 유평, 중산리, 하동과 백무동 지역 자연관찰로의 초본층은 각각 70종, 53종, 65종, 57종으로 이루어져 있다. 종다양도 지수는 교목층 $0.752{\sim}1.162$, 아교목층 $0.957{\sim}1.085$, 관목층 $1.283{\sim}1.506$ 범위인 것으로 분석되었다. 지리산국립공원 내에 조성되어 있는 유평, 중산리, 하동, 백무동 지역 자연관찰로의 균재도는 전층에서 0.752에서 0.983의 범위에 있는 것으로 조사되었다.
