Сосудистые растения и речные бассейны Тюменской области

Abstract

Summary. Tyumen region is located on the West Siberian plain. For a long time, scientists believed this plain is very flat. Therefore, different scientists explained the distribution of plants by the action of natural zones. In fact, the landscape is of great importance in the geography of plants. In the Tyumen region there are several river basins (Irtysh, Tobol, Vagai, Ishim, Turtas, Demyanka). For each river basin district identified the characteristic species of plants found only there. For example, Pyrethrum corymbosum (L.) Scop. was only in the basin of the river Vagai. In the extreme South there are no rivers, there are only lakes. There is also discovered a distinctive species of plants. It is assumed that the confluence of the two rivers will be hot spots of biodiversity. One hot spot is already well – known Tobolsk. The spread of the diaspora is highly dependent on water flows. Therefore, the study of how plant distribution relates to river basins is an important contribution to the development of measures for the protection of rare species.
