森林动态模型概论

讨论了模拟森林林分动态变化的模型，并把模型分为森林生长模型和演替模型。森林生长模型包括：全林分模型、林分级模型和单木模型；演替模型包括马尔可夫类模型和林窗模型。文中给出了演替模型的基本原理和适用性，在比较早期和最新发展的林窗模型后，叙述了林窗模型的新进展。生长和演替模型的结构和数据要求不同决定了它们的在时间和空间上的适应性，最后指出模型将向综合总体方向发展。

Review on Forest Dynamics Models

In this review, models designed to simulate the dynamics of forest stand were discussed and classified into forest growth model and succession model. Forest growth model includes stand models, stand class models and individual tree models; succession model includes Markov-type models and gap models. Principles and application of both Markovian and gap succession models were introduced. The new advance of gap models was stated, after the early and later gap models were compared, with differences being pointed out. The structure and data requirement for growth and succession models affected their spatial and temporal applicability as well as their predictive value. The integration of different kinds of models may be the most general model for predicting tree growth and stand succession dynamics in future.
