摘 要:
森林生态系统碳循环是陆地碳循环研究中的重要内容,碳循环模型已成为研究森林碳循环的必要方法。其中气候变化、大气CO2浓度上升及CH4的生成导致森林生态系统在结构、功能、组成和分布等方面的变化及其反馈关系对森林生态系统碳循环的影响是模型模拟的关键问题。碳循环模型可用经验模型、机理模型和混合模型的建模方法。目前森林生态系统碳循环模型的发展趋势为:综合生物地理模型和生物地球化学模型的特点建立区域动态碳循环模型;从单一碳循环模拟向碳、氮、磷等多种元素循环相耦合的模拟;碳循环模型与遥感、GIS技术结合,模拟大尺度的碳循环过程;CH4生成及对森林碳循环的影响方面的研究。[著者文摘]

Abstract:
Forest ecosystem carbon cycling is one of the important components in the research aspect of terrestrial carbon cycling, and simulation model is a necessary method in understanding the carbon cycling in forest ecosystems. The key processes in the modeling of carbon cycling include the response and feedback of the structure, function, composition and distribution of forest ecosystem to climate change, elevated CO2 concentration and CH4 production. Forest carbon cycling model can beestablished by the method of empirical model, mechanism model or mixed model. The development trend of forest ecosystem carbon model are : combining the elements of biogeographical and biogeochemical models toward the formulation of regional dynamic models of carbon cycling; coupling models of the C, N and P;using RS and GIS techniques for large scale modeling; CH4 production and its effect on the forest carbon cychng.[著者文摘]
