| 摘 要： | 采用双向指示种分类法(TWINSPAN)、除趋势对应分析法(DCA)和典范对应分析(CCA)相结合的方法，对东灵山亚高山草甸进行数量分类和排序，将该草甸分为7个群落类型，分别位于不同的海拔高度。分类结果很好地反映了植物群落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排序轴反映了海拔高度、坡度和垃圾数的梯度变化，表明海拔高度、水热条件和旅游干扰是影响植物群落变化的主要生态因子。CCA排序结果与DCA的排序结果基本一致。

| Abstract: | The meadows in Dongling Mountain are classified and ranked into 7 communities by TWINSPAN,DCA and CCA that are located at different elevation.The results of the classification and ordination reflect the good relationship between plant communities and environmental gradients that is verified at the two-dimension ordination diagram by DCA.The axes of the ordination by DCA reflects the gradient changes in the elevation,the gradient and the number of garbage that altitude,water and heat conditions,the tourism d... |
