| 摘 要： | 在野外样方调查的基础上,采用双向指示种分析法(TWINSPAN)和除趋势对应分析法(DCA)对五台山冰缘地貌植被进行了数量分类和排序研究,将五台山冰缘地貌植被分为13个群丛,13个群丛是不同冰缘地貌生态景观的重要组成要素,各群丛的群落学特征与冰缘地貌生境有密切的生态关系。DCA样方排序结果和种排序结果表明,五台山冰缘地貌植物群落分布格局是土壤、水分、热量等综合环境因子决定的。而不同冰缘地貌上植物群丛优势种的分布格局在很大程度上决定着植物群丛类型的分布格局,反映出植物群落类型和物种分布随冰缘地貌类型及环境梯度变化的趋势。

| Abstract: | Wutai Mountain is located in the northeast of Xinzhou City, Shanxi Province. Its highest peak, with an altitude of 3061 meters, is also the highest peak of North China, hence it was nicknamed "the roof of northern China". Based on the data from the field surveys, the quantitative classification and the ordination of the plant communities related to periglacial landforms on Mt. Wutai were studied by using Two-Way Indicators Species Analysis (TWINSPAN) and Detrended Correspondence Analysis (DCA). The communities were classified into 13 associations by TWINSPAN. The result indicated that the 13 associations were important ecological landscapes elements of different periglacial landforms, and there were close relationships between ecological features of associations and their habitats. The result of DCA ordination showed the relationship between the distribution pattern of plant communities and soil, humidity and energy. And the distribution pattern of dominant species on different types of periglacial landforms dominated the distribution pattern of plant group types, reflecting the changing trend of community types and species distribution with environmental gradient. Compared with mountain communities at the same latitude in China, the vegetation types of Mt. Wutai on periglacial landforms were the most abundant. Moreover, they were unique in the plant species composition of communities. The in-depth studies on the relationship between the regional communities distribution patterns and periglacial landforms environment not only contributed to reasonable protection and development of periglacial landforms, but also was of practical significance in protection of natural landscape and ecological security of Mt. Wutai, which is one of the world cultural heritage sites. |
