Spatial interrelation between biodiversity and habitat types on the territory of the Crimean Peninsula

Abstract

The article presents the study results of the interrelation of diversity of habitat types (locations types) and indicators of biological diversity at the local spatial level (operational-territorial units are specially protected natural reservations). The work is based on data on 58 specially protected natural reservations for which there is information on biological diversity. On the basis of remote sensing data, those are published and archive materials for each specially protected natural reservations, cartographic models of habitat types and a geoinformation database on their biological diversity are obtained. The analysis of their spatial differentiation is carried out. Derived indicators of habitat diversity and species richness (Margalef’s and Menhinik’s species richness indexes) are calculated on the basis of the obtained layers and database. The map models of variety of base locations, indexes of the diversity of locations within protected areas, basic indicators of biodiversity, variety of rare and endemic species, biodiversity indexes within protected areas network elements are obtained. On the basis of the obtained spatial database, correlations between the habitats diversity and the value of biodiversity at the local level are determined. The calculated spatial interrelation coefficients of location diversity and biological diversity show a sufficiently high level of interrelation: from 0.48 to 0.83. The correlation values (both linear and rank) are quite high, which confirms the hypothesis that there is a close interrelation between the biological diversity of the Crimean Peninsula territory and the habitats diversity from which it consists.
