中文摘要：

全球植被动力学模型（DGVM）是研究陆地生态系统碳循环过程的重要手段，是进行植被动力学模拟的有效工具．本文对DGVM的发展进行概述，探讨了DGVM的基本结构，介绍了国际上应用较广泛的CLM—DGVM、LPJ、IBIS和SEIB模型，并针对植被动力学机制指出了DGVM在植被功能型方案、植被竞争、干扰和物候方面普遍存在的不足．最后，文章从改善植被功能型方案、完善植被动力学机制和开展模型比较计划方面，对DGVM研究方向进行了展望．

英文摘要：

Dynamic global vegetation model （DGVM） is an important and efficient tool for study on the terrestrial carbon circle processes and vegetation dynamics. This paper reviewed the develop- ment history of DGVMs, introduced the basic structure of DGVMs, and the outlines of several world-widely used DGVMs, including CLM-DGVM, LPJ, IBIS and SEIB. The shortages of the de- scription of dynamic vegetation mechanisms in the current DGVMs were proposed, including plant functional types （PFT） scheme, vegetation competition, disturbance, and phenology. Then the fu- ture research directions of DGVMs were pointed out, i.e. improving the PFT scheme, refining the vegetation dynamic mechanism, and implementing a model inter-comparison project.
