| 摘 要： | 采用双向指示种分析法（TWINSPAN）和除趋势对应分析法（DCA）对长江故道湿地植被做分类和排序研究。TWINSPAN分类将湿地植被234个样方分为28个群丛,论述了各群丛的群落学特征。DCA排序结果反映了植物群落类型与环境梯度之间的关系,表明影响群丛分布格局的主导生态因子为生境的水分条件。TWINSPAN数量分类在DCA排序图中有较为明确的分布范围和界限,两者的结合使用,能很好地反映群落与环境因子间的生态关系。

| Abstract: | The classification and ordination of wetland vegetation in the Tian'ezhou Oxbows of the Yangtze River were studied using two-way indicator species analysis(TWINSPAN) and detrended correspondence analysis(DCA).A total of 234 samples collected from the wetland vegetation in the Tian'ezhou Oxbows were classified into 28 associations by TWINSPAN and the community characteristics of every association were described.The DCA ordination reflected the relationship between plant community type and the environmental g... |
