초록

본 연구는 가야산국립공원을 대상으로 지리정보시스템(Geometric Information System, GIS)을 이용 식생분포에 영향을 미치는 요인들을 분석하여, 식생분포 확률을 기초로 가야산국립공원의 잠재자연식생을 추정하였다. 가야산국립공원의 현존식생조사 결과 128개의 군락이 분포하는 것으로 나타났다. 가야산국립공원의 고도, 경사, 사면방위, 지형지수, 연평균 온도, 온량지수, 잠재증발산량의 7개 요인을 중심으로 군락별 분포를 분석하였으며, 이를 바탕으로 분포확률을 추정하였다. 잠재자연식생의 분포확률이 0.3이상인 군락은 소나무군락의 출현확률이 55.80%로 가장 높았으며, 신갈나무군락이 44.05%, 상수리나무군락이 0.09%, 굴참나무군락이 0.06%로 나타났다. 식생의 분포에 영향을 주는 요인을 본 연구에서 제시한 요인으로 한정할 경우 가야산국립공원의 잠재자연식생은 신갈나무군락(43.1%)과 소나무군락(56.9%)이 나타날 것으로 예측되었다.

This study estimated potential natural vegetation in Gayasan National Park through the occurrence probability distribution by using geographic information system (GIS). in Gayasan National Park. Correlation and factor analysis were analyzed to estimate probability distribution. The presence of the Gaya National Park Vegetation survey results showed that 128 communities were distributed. The analyzed relationship between actual vegetation and distribution factors such as elevation, aspect, slope, topographic index, annual mean temperature, warmth index and potential evapotranspiration in Gayasan national park. The probability distribution of potential natural vegetation communities at least 0.3 odds were the advent of Pinus densiflora communities with the highest 55.80%, Quercus mongolica community is 44.05%, 0.09% is Quercus acutissima communities, Quercus variabilis communities are found to be 0.06%. If you want to limit the factors that affect the distribution of vegetation by factors presented in this study, the potential natural vegetation of the Gaya National Park was expected to appear in Quercus mongolica community (43.1%) and Pinus densiflora communities (56.9%).
