摘　　要：通过研究了模拟林分的方法,发现存模拟林分方法中缺少一种共性的机制。没有通过利用林分结构作为模拟林分的规则,只是通过定性的模拟而不是将模拟指标量化,主要通过人为设定并且不能对于混交林进行模拟,缺乏合理性、真实性、广泛性。本研究提出了一种基于空间结构的林分模拟方法,通过量化的林分结构指标模拟林分来模拟林分,为林业科研工作与经营管理提供更可靠的模拟数据来源。Through researching the methods of stand simulation, it was found that there is a lack of common mechanism in the simulation rules. The methods did not use the stand structure as rules of the simulations and most of them depend on the qualitative simulation instead of the quantitative simulation. Due to mainly through manually setting, the methods cannot simulated for mixed stand, the methods were lack of rationality, authenticity, universality. This study presents a simulation method based on the spatial structure of the stand, quantifies forest structure indicators simulation stands for forestry research work and provides management of simulation data sources.
