摘　　要：根据植物种群生物量的增长模式和最大密度法则 ,应用Korf生长方程推导出同龄纯林最大密度的林分和一般密度的林分在自然稀疏过程中密度变化规律的模型。实例验证表明 ,本文所提出的自然稀疏模型有较高的准确性和较大的适用性 。The model of density variation during the self thinning process for maximal density stand and general density stand was reduced by using Korf growth equation according to the growth model of biomass of plants population and maximal density,and it was proved that the self thinning model proposed in the article had more accuracy and practicability and could be used in simulating stand density development of various natural growth.
