摘要: 梭梭(Haloxylon ammodendron)是准噶尔盆地沙漠植被中最重要的优势植物。根据对准噶尔盆地典型梭梭植物群落样地的物种及群落状况的调查,采用数量分类的方法对该地区梭梭植物群落的相似性进行了聚类分析。聚类分析的结果表明, 37个梭梭群落被划分为11个群丛,根据聚类过程阶梯图的结果, 11个群丛进一步划归为5个群系。研究结果与传统的植物群落分类结果基本相一致,对于更好地保护和恢复梭梭植被具有一定的实践指导意义。

关键词: 梭梭植物群落, 相似性, 聚类分析, 群丛, 群系

Abstract: Haloxylon ammodendron was the most important dominant plant in Junnger basin.On the basis of investigation results of typical Haloxylon ammodendron communities, the classification of these communities was carried on according to the similarity among communities by using numerical cluster.The results suggested that all 37 communities were included in 11 plant associations.According to the results of cluster analysis, 11 plant associations were included in 5 formations.The results of classification analysis were basically consistent with the traditional classification of Haloxylon ammodendron communities.The researching results was meaning for protection and restoration of Haloxylon ammodendron community in the future.

Key words: Haloxylon ammodendron community, similarity, classification analysis, association, formation
