| 摘 要： | 在野外植被调查的基础上,应用TWINSPAN分类和DCA排序法,对川西北高寒草地退化演替群落进行了多元分析.根据TWINSOAN分类结果,并结合生态特性,将所调查的45个样方植被分为12个群丛,论述了各群丛的群落学特征.DCA二维排序图较好地验证了TWINSPAN的分类结果,第1轴主要反映了植物群落所在环境的水分条件梯度,第2轴基本反映了高寒草地不同退化的梯度.

| Abstract: | Based on the field investigation,TWINSPAN(Two-way indicator species analysis) and DCA(Distended correspondence analysis) were adopted to conduct the multi-analysis of degeneration succession community on alpine grassland under degenerate succession in north-west of Sichuan province.According to the results of TWINSPAN and in combination with the ecological characteristics of the region,45 sampling plots were divided into 12 associations,and their community characteristics were described.The result of DCA or... |
