摘要：

Self-thinning models were developed to describe the relationship between the stem number and mean diameter of even-aged and monospecific tree stands undergoing self-thinning. The models were developed separately for Pinus sylvestris L., Picea abies (L.) Karst. and Betula pendula Roth. stands. Data from 41 unthinned permanent sample plots were used. According to Reineke's equation and the -3/2 power rule of self-thinning, a log-log plot of average tree size and stem density will give a straight, self-thinning line of constant slope. According to this study, the slope of the line consistent with Reineke's equation varies for different tree species. Within tree species, the intercept of the self-thinning line varies according to site index.
