Abstract

As climate change intensifies, the importance of studying plant phenology has increased, leading to a surge in research employing automated video recording devices like Phenocams. In this study, using the Phenocams operated by the National Institute of Ecology, we examined the trends in plant phenological changes across diverse ecosystem types in South Korea and analyzed their correlations with climate factors. The patterns of plant phenological changes varied by region and tree species. Pinus thunbergii and Pinus densiflora typically show an overall increase in their growth period, positively correlating with temperatures and precipitation during winter. However, uniquely, for Abies koreana on Hallasan Mt., a higher amount of precipitation in August leads to an earlier end of season (eos), and the correlation analysis with the recent phenomenon of dying A. Koreana seems necessary. beyond the analysis, solutions for handling missing data issues during the data collection process were proposed. Furthermore, to expand future research scope and encompass diverse ecosystem types, a suggestion to combine Phenocam research with satellite observations was presented.

기후변화가 심화됨에 따라 식물계절연구의 중요도가 증가하고 있으며 자동영상촬영장치 (피노캠, Phenocam)을 활용한 연구방법이 급부상하고 있다. 본 연구에서는 국립생태원에서 운영하는 피노캠을 활용하여 국내 주요 생태계 유형에 대한 식물계절 변화의 경향을 확인하고 기후요인과의 상관관계를 분석했다. 식물계절의 변화 양상은 지역 및 수종별로 다르게 나타났다. 곰솔 및 소나무림은 전체 생장 기간이 증가하는 경향을 보이며 주로 겨울철 기온과 강수량과 양의 상관관계를 보였으나, 한라산 구상나무는 8월 강수량이 많을수록 생장종료일이 빨라졌으며 최근 발생하는 구상나무 고사 현상과의 연관성 분석이 추후 필요할 것으로 보인다. 분석 결과에서 더 나아가 데이터 수집 과정에서 발생할 수 있는 결측치 문제 등에 대한 해결책을 제시하였으며, 향후 연구 범위를 확장하고 다양한 생태계 유형을 반영하기 위해 피노캠 연구와 위성 관측을 결합하는 방안을 제안하였다.
