Аннотация: The paper deals with some results of a comparative study of the similarity and dissimilarity of landscape structure and floras in the landscape and floristic microregions as lower units of regionalization. The Kasmalinsky and Barnaulka river basins at the Ob plateau in Altai Krai are used as model objects. These catchments represenПоказать полностьюt an ancient flow gullies changed by fluvial erosion and neotectonics. The study area is characterized by geological-geomorphological (terraces of the ancient flow gullies), zonal (droughty steppe, temperate-droughty steppe and southern forest-steppe) and the basin (endorheic lake basin and basins of the Ob river tributaries) heterogeneity. That makes it unique and extremely promising for comparative geographical studies. To explore the similarities and dissimilarities in the landscape structure proposed to use quantitative measures of similarity (e.g., Czekanowski measure), which can be the basis for actual landscape regionalization at the lower regional level when constructing the hierarchy bottom-up. In other words, the landscape microregions initially identified by morphological (structural) and secondary parameters can be combined into subregions and regions according to the strength of connections. The connections between the floras of the microregions show smoother and more regular changes than between their landscape structure. However, the differences in landscape structure can be justified more confidently than the differences in the floras because in the first case we have already formalized characteristics of the specific differential types of landscape units, and in the second one we deals with specific species of higher vascular plants which differential ability are often questionable due to uncertainty of factors limiting their distribution.
