摘要/Abstract

摘要： 利用双向指示种分析法（TWINSPAN）和除趋势对应分析（DCA）对昆嵛山不同林分类型下的灌木层和草本层进行了数量生态学分析. TWINSPAN分类将灌木层和草本层分别分为14个类型和10个类型，分类的结果与林分类型之间存在着较好的对应关系. DCA排序将不同林分下的灌木层和草本层都分为了4个生态类型，其中，灌木层生态类型的区分环境因子是光照和水分，而草本层生态类型的区分环境因子则是水分. 不同林分类型下的物种多样性指数并不是都存在显著差异，只有Gleason丰富度指数和Shannon-Wiener多样性指数在不同林分间的差异达到显著.

Abstract: The TWINSPAN classification and DCA ordination were employed for the quantitative analysis of the shrub layer and herbage layer under different stands. The shrub layer and herbage layer were classified into 14 and 10 types by the TWINSPAN classification method, which indicated that classified types of the shrub layer and herbage layer highly correspond to the type of the stand. The quadrats of the shrub layer and herbage layer were both coordinated into four ecological types in the space of the DCA ordination. The foremost environmental factors in the DCA ordination of shrub layer is illumination and moisture, while for the herbage layer it is moisture. Under different stands, not all the biodiversity indices are significantly different, while the Gleason index and Shannon-Wiener index are significantly different among different stand types.

Key words: Kunyu Mountain , biodiversity, herbage layer, shrub layer, DCA ordination, TWINSPAN classification
