| 摘 要： | 根据Lotka Volterra种间竞争的原理确定混交比例。结果表明 :目的树种 (杉木 )与混交树种的混交比例依混交树种不同而异 ,目的树种与同一混交树种的混交比例亦因立地条件而变化 ,它们的混交比例的变动系数依混交树种而异。采用这种方法得出目的树种与混交树种的混交比例 ,具有一定的科学性。

| 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. |
