Abstract

The purpose of this study is to analyze sensitivity of forest ecosystem to climate change using spatial analysis methods focused on 6 national parks. To analyze, we constructed MODIS NDVI and temperature of Korea Meteorologic Administration based on 1km spatial resolution and 16 days. And we conducted time-series and correlation analysis using MODIS NDVI and temperature. A most sensitive region to climate change is Jirisa National Park(r=0.434) and Seoraksan National Park(r=0.415), there is the highest mean correlation coefficient. The sensitivity of forest ecosystem varied according to habitat characteristics and forest types in national park. In Abies koreana of Hallsan Nation Park, temperature has raised, but NDVI has decreased. these results will be based data of climate change adaption policy for protecting forest ecosystem.

본 연구는 공간분석기법을 활용하여 6개 국립공원지역을 대상으로 기후변화에 따른 산림생태계 민감성을 분석하였다. 분석방법은 공간해상도 $1km{\times}1km$와 16일 단위의 MODIS NDVI와 기상청 남한상세 기온자료를 활용하여 시계열 분석 및 상관분석을 통해 도출하였다. 기후변화에 가장 민감한 지역은 평균 상관계수가 가장 높은 지리산 국립공원(r=0.434)과 설악산 국립공원(r=0.415)으로 나타났다. 기후변화에 의한 산림생태계의 민감성은 국립공원 내 식생유형 및 서식지의 특성 등에 따라 상이한 것으로 나타났다. 특히 한라산 국립공원의 구상나무 군락지에서는 기온이 증가하는 반면, 식생지수는 감소하는 것을 알 수 있었다. 이는 구상나무가 기후변화에 취약한 종임을 선행연구와 비교를 통해 증명되었다. 이와 같은 결과는 향후 산림생태계 보호를 위한 기후변화 대응 및 적응정책을 마련하는데 기초적인 자료로 활용될 것으로 판단된다.
