Influence of morphometric parameters of river basins on taxonomic richness of flora (by the example of the Tom river basin)

The article deals with methodological issues of studying the influence of morphometric parameters of model basins (size, nature of the river network, shape) of the Tom river on the taxonomic structure of flora. Taking into account significant differences in the morphometric of river basins, which determine the diversity of environmental conditions in the Tomi river basin, 22 model basins were identified. Morphometric of model basins is determined by 25 parameters characterizing the main sizes of basins (area, length, width, height, etc.), features of the river network (length and number of rivers, etc.), as well as various forms of river basins. The indicators of floristic wealth are accepted: the number of species, the number of genera and the number of model pool families. The author considers the conditionality of taxonomic diversity of flora by morphometric characteristics of basins for three levels-species, genus and family. Morphological parameters of model basins vary widely, which determines the diversity of plant habitats...
