Abstract:

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.
