【摘要】	在群落样方调查的基础上,采用TWINSPAN分类和DCA排序相结合的方法,对太原市崛围山人工植物群落的群落组成、结构、空间分布进行了分析。TWINSPAN分类将崛围山45个样方划分为7个群丛,各群丛分别位于不同的海拔高度,并论述了各群丛的特征。分类结果反映了植物群丛类型与环境梯度之间的关系,并在DCA二维排序图上得到了较好的验证,DCA排序轴反映了海拔和坡向的梯度变化,表明海拔和坡向是决定群落分布的主导因子。
【英文摘要】	Based on the field investigation,Two-way indicator species analysis(TWINSPAN) and distended correspondence analysis(DCA) were applied to analyze the composition,structure and special distribution of the artificial plant communities in Quwei mountain of Taiyuan.45 samples were classified by TWINSPAN into 7 associations at different altitudes.The characteristics of every association were described.The classification results well reflected the relationship between the types of plant communities and environment...
