Ecosystem models are mathematical representations of underlying mechanistic relationships among ecological components and processes. Ecosystem modeling is a useful tool to visualize inherent complexities of ecological relationships among components and the characteristic variability in ecological sy...

생태모델이란? | 생태모델은 생태계의 구성 요소간의 관계를 미분 방정식을 사용하여 수치적으로 표현한 형태이다. 일반적으로 생태계 구성요소로는 물리, 화학적 환경 요인 및 생물학적 환경 요인 등이 있다. | |
생태계 구성요소는? | 생태모델은 생태계의 구성 요소간의 관계를 미분 방정식을 사용하여 수치적으로 표현한 형태이다. 일반적으로 생태계 구성요소로는 물리, 화학적 환경 요인 및 생물학적 환경 요인 등이 있다. 생태모델은 생태계 내에 존재하는 이러한 다양한 요인들을 상태변수로 간주하여 시간에 따른 상태변수 간의 관계 및 양적 변화를 추정 및 예측하는데 유용한 도구라 할 수 있다. | |
JGOFS은 어떤 목적으로 만들어졌는가? | JGOFS (Joint Global Ocean Flux Study)는 1980년 후반에 시작되어 2000년 초반에 끝난 대표적인 해양 국제협력 프로그램 중하나이다. 이 프로그램은 전지구적 규모의 탄소 및 생명활동과 관련된 원소들의 대기, 해양 및 육상 간의 순환작용을 결정짓는 주요 요인을 파악하고 기후 변화 및 인간활동으로 인해 발생하는 교란이 해양 생지화학적 순환에 어떠한 영향을 미치는 지를 예측하기 위한 목적으로 만들어졌다. 이 프로그램은 해양학의 학제간 결합을 이용한 종합적인 현장 관측 및 실험, 이를 통한 장기 자료의 구축, 또 마지막으로, 이렇게 해서 축적된 결과를 이용한 모델의 개발이라는 체계적인 접근 방법을 채택하여 성공한 대표적인 사례이다. |
