摘要: 用传统林分结构因子配合角尺度、混交度、大小比3个参数来分析北京八达岭林场灌木林空间结构特征。结果表明:1)主要灌木种类有荆条(Verbenaceae)、山杏(prunus armniacaL)、小叶鼠李(Rhamnus parvifolia)、绣线菊(Spiraea salicifolia L.)、胡枝子(Lespedeza bicolor Turcz.);2)灌丛冠幅体积随海拔升高而减小,阳坡灌丛冠幅体积大于阴坡;3)灌木种混交度与灌木丛数在整个林分中所占的比例有关,比例增大混交度减弱;4)灌丛高度大小比数排序为:绣线菊>胡枝子>小叶鼠李,灌木种的灌丛大小比数主要与自身的生物学特性有关。

Abstract: On the basis of the traditional stand structure indexes and three spatial structure indexes including the mingling, neighborhood pattern and neighborhood comparison as the indicators, spatial structure of the shrubbery stand is analyzd. 1)Research shows the main species include Verbenaceae, prunus armniacaL, Rhamnus parvifolia, Spiraea salicifolia L and Lespedeza bicolor Turcz.; 2) shrub crown volume decreases with elevation;the shrub crown volume on the south slope is bigger than that on the north slope; 3) mingling of shrub species is related with the species proportion in the stands, and the mingling decreases with the proportion; 4)the height neighborhood comparison ranking is Spiraea salicifolia L. > Lespedeza bicolor Turcz. > Rhamnus parvifolia,which is related with species biological characteristics.

Key words: shrub stand, mingling, neighborhood pattern, neighborhood comparison
