Abstract

It has actively advanced to study the impact of climate change on ecosystem. This study addresses ABMS (Agent Based Modeling and Simulation) as a methodology of ecosystem research. ABMS would suggest the possibility of practical use in this sector. This study would investigate how the melting speed of glacier in the arctic influences the extinction period of polar bears. The Polar Bears and Glacier Model in this study is expected to contribute to accurate prediction of the polar bear's extinction period. The suggested ABMS could also be applied to the study of various factors of ecosystem in general.

최근 기후 변화에 따른 생태계의 변화에 대한 연구가 활발히 이루어지고 있다. 본 연구는 생태계 연구에 새로운 연구방법으로서 행위자 기반 모델(ABMS)을 소개하고, 사례연구를 통해 이 분야에 대한 활용 가능성을 제안하고자 한다. ABMS의 활용 가능성을 제안 평가하기 위하여, 기후 변화로 인한 빙하의 감소와 그에 따른 북극곰의 멸종 위기에 대해서 에이전트기반의 모형을 수립하고 모의실험을 실행하였다. 연구 결과는 중요 변수 간 상호작용에 신뢰할 만한 일관성을 발견할 수 있었다. 이러한 연구 결과는 제안한 빙하-북극곰 모델이 환경 변화에 따른 북극곰 멸종 시기 예측에 기여할 것을 기대할 수 있게 한다. 이에 따라, ABMS는 생태계의 다양한 변화 과정의 분석 일반에 적용이 가능할 것을 기대할 수 있다.
