| 摘 要： | 灌木层植物种类丰富，成层明显，结构复杂是俄罗斯平原针阔混交林群落的突出特点，应用Ｘ＾２检验和Ｐｅａｒｓｏｎ相关系数ｒ公式研究了灌木层植物种间联结和相关性，对测定结果的生态学意义进行了分析，依据测定结果，将形成灌木层的植物划分为４个生态联结种组；俄罗斯金雀花＋璎珞柏，欧洲白蜡＋欧洲白榆，疣枝卫矛＋欧洲荚迷＋黄忍冬＋欧榛子＋黑茶镳子＋欧洲赤杨。生态种组的划分为整个群落的结构和动态研究及植被的恢复和重建

| Abstract: | The abundant shrub species,obvious
stratifications and complex shrub layer structures,which are the most outstanding
characteristics in the coniferous broad mixed forest in the Russia plain. X 2 and r
formulae are used on studying the interspecific association and correlation of shrub
layer.Based on analytical results of X 2 and r formulae,plants of shrub layer can be
divided to 4 ecological species groups: Cytisus fish Juniperus communis,Fraxinus
excelsior Ulmus laveuis,Euonymus verrusonca Vibunum opulus Lonicera xylosteum Corylus
avellana and Ribes migrum Padus racemosa Alnus glutinosa. This kind of classificaton will
provide an important theory basis on studying structure and dynamics of forestry
community,and vegetation recover and restoration. |
