| 摘 要： | 以太行山南段峡谷区荆条Vitex negundo群落为对象，沿不同海拔布置样方，应用TWINSPAN和DCA相结合的方法，对样方进行数量分类和排序，并进行了环境解释。TWINSPAN等级分类把47个样方分为11个群丛，DCA排序结果同TWINSPAN分析结果相吻合。DCA结果揭示出，其中第一轴显著地反映出各个群系的坡向变化趋势，而第二轴则反映出坡度的梯度变化,表明样方所在地的坡向和坡度是决定群丛分布的主要环境因素。

| Abstract: | The ecological relationship of species,community and environment of Vitex negundo var.heterophylla communities were studied by using TWINSPAN and DCA.The results of TWINSPAN indicates that the communities could be classified into 13 associations.The classification matrix indicates two environmental gradients,light intensity and soil humidity.The gathered groups of plant quadrates in the space of DCA ordination are consistent with the result of TWINSPAN,which revealed a relationship between plant formations ... |
