加拿大碳收支模型（CBM-CFS3）原理、结构及应用

CBM-CFS3模型基于森林资源清查数据，可模拟不同尺度、不同干扰或经营措施下森林生态系统的碳储量及变化，满足IPCC温室气体最高层次计量方法的要求，是IPCC推荐使用的碳计量模型。该模型的应用将会对我国森林碳储量估算产生重要的促进作用。文中主要介绍CBM-CFS3模型的发展历程和特点、原理、运行和数据结构以及模型目前的应用研究情况，评价了当前模型的适用范围和局限性。

Principle, Structure and Application of Carbon Budget Model (CBM-CFS3) in Canada

At present, there is no precise model in China, which can be used to calculate carbon stocks at nation scale. CBM-CFS3 model, which can simulate the carbon stocks and their dynamics in forest ecosystem at different scales or in different scenarios of disturbances and management practices, meets the requirement of IPCC's highest level in carbon accounting; therefore it is recommended by IPCC. The application of this model in China would greatly enhance our ability to calculate carbon stocks in China's forests. The paper mainly introduced the development history of CBM-CFS3 and its characteristics, theory, operation and data structure, and described the current application and research of the model. Finally, the model was evaluated for its applicable scope and limits.
