| 摘 要： | 采用双向指示种分析法(TWINSPAN)和除趋势对应分析法(DCA)对汾河临汾段湿地植被做了分类和排序研究.TW INSPAN分类将湿地植被82个样方分为16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土壤水分和海拔高度.

| Abstract: | The classification and ordination of the wetland vegetations in Linfen Section,Fenhe River were studied using two way indicator species analysis(TWINSPAN) and detrended correspondence analysis(DCA).Eighty two samples collected from the wetland vegetations in the Fenhe River were classified into 16 associations by TWINSPAN and the community characteristics of every association were described as well.The result of DCA ordination has reflected the relationship between plant community type and the environment gradient.The result shows that distribution pattern of the associations were mainly affected by the leading ecology factor of the water gradient of soil and the altitude gradient. |
