摘要: 陆地碳循环是全球变化研究中的重要内容,碳循环模型已成为研究陆地碳循环的必要方法。其中气候变化、大气CO2浓度上升以及人类活动引起的土地利用和土地覆盖变化导致陆地生态系统在结构、功能、组成和分布等方面的变化及其反馈关系对陆地碳循环的影响是模型模拟的关键问题。生物地理模型和生物地球化学模型是碳循环模型的两大类型,建模方法、模型性质、特点和应用范围各异。碳循环模型的发展方向是综合两类模型的特点,建立全球动态碳循环模型。

关键词: 陆地生态系统, 碳循环, 模型

Abstract: Terrestrial carbon cycling is one of the important components in the research of global change, and simulation modeling is a necessary method in understanding the carbon cycling in terrestrial ecosystem.The key processes in the modeling of carbon cycling include the response and feedback of the structure, function, composition and distribution of terrestrial ecosystem to climate change, elevated CO2 concentration and human induced land use/cover change.Biogeographical and biogeochemical model are the two kinds of models in modeling carbon cycling, which differentiate in the way of model establishment, character and domain of model application.The developmental direction of carbon cycling modeling is to combine the elements of both kinds of models toward the formulation of global dynamic model of carbon cycling.
