摘要

首次确定了贝加尔湖-戈壁样带草原植被的分类学多样性,包括23个组、5个区系、3个生态历史序列的49个群落。根据生态-植物群落优势-决定原则进行分类构建,以野外调查数据为基础,采用传统的地理植物学方法:路线勘测研究、地理植物学描述、聚类和梯度分析。该方法的单元反映了群落在演替的某一阶段的现状,句法反映了该地区固有植被的生态特征。这种方法具有一定的应用价值,特别是在制图方面——与生态-植物区系方法相比,主要句法类群的体积更小,这使得在大规模制图中进行更有意义的分析成为可能。

Analysis of phytocoenotic diversity of steppe vegetation of the Baikal-Gobi transect
For the first time, the syntaxonomic diversity of steppe vegetation along the Baikal-Gobi transect was determined, represented by 49 associations belonging to 23 formations, 5 florocoenotypes, and 3 ecological-historical series. The classification construction according to the ecological-phytocoenotic dominant-determinant principle was based on data collected during field research and processed using traditional geobotanical methods: route reconnaissance studies, geobotanical descriptions, cluster and gradient analysis. Units of this approach give an idea of the current state of communities at a certain stage of succession, and syntaxa reflect the ecological features of vegetation inherent in the territory. This approach has an applied value, expressed, in particular, in mapping – the volume of the main syntaxa is smaller compared to the ecological-floristic approach, which makes it possible for a more meaningful analysis in large-scale mapping.
