Phenomenological models of the forest plantations growth are analyzed. Those derived from the Verhulst's model are shown to fail describing qualitative effects reflecting tree growth, phytomass withdrawals, and plantation restoration. The method of phase portraits is used for exploration of the forest ecosystem dynamics, which allows to describe regulatory mechanisms of the growth processes, regulation delay, and feedback types. A bistable phenomenological model is suggested herewith to characterize dynamic processes in the forest ecosystems. Principal patterns of formation of the forest plantations at different stages of the forest generation processes are considered on the basis of that model, and ecological effects responsible for the plantation dynamics are revealed.
分析了人工林生长的现象学模型。结果表明，那些源自Verhulst模型的模型无法描述反映树木生长、植物量提取和人工林恢复的定性效应。利用相图方法探索森林生态系统动态，该方法能够描述生长过程的调节机制、调节延迟和反馈类型。据此提出了一个双稳态现象学模型来表征森林生态系统中的动态过程。基于该模型，考虑了森林生成过程不同阶段人工林形成的主要模式，并揭示了导致人工林动态变化的生态效应。
