Biological diversity and spatial structure of the anthropogenic landscape flora

Abstract

The article considers the biodiversity and spatial structure of the urban flora as a complex phenomenon formed as a result of the interaction of natural and anthropogenic ecosystems. The data of the chorological analysis of the urban flora demonstrate the genesis of the species diversity and the relationship with other botanical and geographical areas, while being of great importance in predicting the ways of its formation. The purpose of this research was to study and analyze the spatial distribution of the flora species composition of Sosnovoborsk (south of Central Siberia, Krasnoyarsk Territory). The study of plant biodiversity was carried out using a special research method of urbanized territories - the model allocation method in combination with traditional route surveys. The types of areas and their elements were determined using the literature data of fundamental floristic and monographic summaries. In the course of the analysis, the types of areas identified by other authors studying the floras of various Siberian regions were taken as a basis. As a result of the study, 387 species of vascular plants were determined, distributed in 231 genera and 62 families. The chorological analysis showed the dominance of Eurasian and Euro-Siberian geographical elements, as well as the belonging of the flora of Sosnovoborsk to the subboreal type, formed on the basis of forest-steppe with a high activity of boreal species.
