Abstract

Abstract:

The mixed proportion was decided based on principle of Lotka-Volterra interspecific competition.The results showed that:the mixed proportion between Chinese Fir and its mixed tree species changed in terms of different tree species and the proportion between purpose tree species and one same mixed tree species changed according to different groups of site type,and the variation coefficients of the mixed proportion changed with the tree species used for mix.Morever comparing with traditional methods this new method was more scientific than other old ones.

Key words: Lotka-Volterra model, Competition, Mixed forests, Mixed proportion
