分析了系统林学、系统森林学研究对象所涉及到的系列复杂现象。特别从现代林业工程系统和非线性动力学的角度,简要分析了复杂现象出现的内在动力学机理,并在研究方法上就如何和现代非线性科学结合,作了一些讨论,对于在系统林学、系统森林学的基础上,建设现代林业工程学具有一定的意义。 This paper analyzes a series of complex phenomena involved in systematic forestry and systematic forest research. In particular, from the point of view of modern forestry engineering system and nonlinear dynamics, this paper briefly analyzes the inherent dynamic mechanism of complex phenomena and makes some discussions on how to combine them with modern non-linear science. In the field of system forestry, Based on systematic forest science, it is of some significance to construct modern forestry engineering.
