摘  要:
森林动态模型分为经验模型和过程模型.混合模型是两者的结合,既具备两者的优势,又规避了它们的缺陷.FVS-BGC是森林植被混合模型的一个典型代表,它是经验模型FVS与生理过程模型Stand-BGC的结合.文中重点阐述了FVS-BGC的基本原理和发展过程,当前该模型多应用于树木活力的评估方面,且主要用于对针叶树种动态过程的模拟,但在阔叶树种的模拟上也具有很大的推广潜力.

摘  要:
Forest dynamic models were discussed and classified into empirical models and process models.Both of them were explained explicitly and traits of the hybrid were also illustrated.The hybrid model couples the above two kinds of models,which has their advantages and avoids the disadvantages.FVS-BGC is one of the representative hybrid modle of forest vegetations,which is the combination of empirical model of FVS and the physiological process model of Stand-BGC.The paper stated the main principles and applications of FVS-BGC and pointed out that the model is mainly used to assess trees vigor and in particular used in the simulation of dynamic process of conifers,but it is also of great potential in simulating the dynamic of broadleavesd trees.Some problems in the models and the future developing direction were pinned down.
