초록

한반도의 기후변화가 산림생태계에 미치는 영향을 분석하는 것은 난아열대 산림생명자원 관리에 중요하다. 본 연구에서는 난아열대 목본식물인 소귀나무와 Syzygium buxifolium의 위치자료와 생물기후변수를 수집하고, 수집된 자료를 바탕으로 MaxEnt 모형에 적용하여 잠재분포 영역을 추정하였다. 소귀나무의 분포를 결정하는 주요 환경인자는 가장 따뜻한 분기의 강수와 온도 계절성이고, Syzygium buxifolium의 주요 환경인자는 가장 따듯한 분기의 강수와 가장 습한 분기의 강수로 나타났다. MaxEnt 모형의 행정구역별 결과, 소귀나무는 SSP2-4.5 기후변화 시나리오에서 4.6 - 17.7%의 면적 증가율을 보였고, SSP5-8.5 기후변화 시나리오에서 13.8 - 30.5%의 면적 증가율을 보였다. Syzygium buxifolium는 SSP2-4.5 기후변화 시나리오에서 4.8 - 32.2%, SSP5-8.5 기후변화 시나리오에서 12.9 - 48.6%의 면적 증가율을 보였다. 본 연구는 기후변화 시나리오를 적용하여 난대아열대 식물의 미래 잠재분포 영역을 확인하고 데이터베이스를 구축하는데 의의가 있다.

Analyzing the impact of climate change on the Korean Peninsula on the forest ecosystem is important for the management of subtropical forest bioresources. In this study, we collected location data and bioclimatic variables of the warm-temperate woody plant species, Myrica rubra and Cyzygium buxifolium, and applied the MaxEnt model based on the collected data to estimate the potential distribution area. Precipitation and temperature seasonality in the warmest quarter were the main environmental factors that determined the distribution of M. rubra, and the main environmental factors for S. buxifolium were precipitation in the warmest quarter and precipitation in the wettest quarter. The results of the MaxEnt model by administrative district, the M. rubra showed an area increase rate of 4.6 - 17.7% in the SSP2-4.5 climate change scenario and 13.8 - 30.5% in the SSP5-8.5 climate change scenario. S. buxifolium showed area increase rates of 4.8 - 32.2% in the SSP2-4.5 climate change scenario and 12.9 - 48.6% in the SSP5-8.5 climate change scenario. This study is meaningful in establishing a database and identifying future potential distribution areas of warm and subtropical plants by applying climate change scenarios.
