| 摘 要： | 以R=K+W作为计测二维分异的经验公式。结果表明:W值影响群落的乔木层种类,(K+W)值影响林下的种类组成和配置状况。据W值大小和群落的特征,将青杄林分为五个群类型;(K+W)值对选择造林树种和抚育间伐具有一定的指导意义。

| Abstract: | Determines the effect of 2-dimensional difference of light intensity on stand structure and community type of Picea wilsonii forest by using R = K + W as an empirical formula .W value affects the species of tree stratum in the community where (K+ W) value affects the species composition and distribution. Picea wilsonii forest may be classified into 5 community types based on W value . (K + W) value is specified for selecting tree species in forestation and tending thinning. |
