Ogureeva G.N.,  Bocharnikov M.V.,  Suslova E.G. STRUCTURE OF THE CRIMEAN-NOVOROSSIYSK OROBIOME (THE UTRISH-TUAPSE VARIANT) BOTANICAL DIVERSITY // Arid ecosystems. 2020. V. 26. № 4 (85). P. 10-17. | PDF

Based on the concept of ecosystem diversity, a regional assessment of the Crimean-Novorossiysk orobiome is given. Orobiome is considered to be a strong unit for inventory and analysis of mountain biodiversity. On the example of the Utrish-Tuapse geographical variant of the orobiome (the Northwest Caucasus), the altitudinal-belt structure of the vegetation cover is revealed, according to which the spatial differentiation of flora and plant communities are formed. A quantitative evaluation of biota and abiotic indicators characterizing the botanical and geographical traits of the orobiome is given. The spectrum of altitudinal zonality of vegetation is determined, a quantitative assessment of floristic diversity by the belt is given, and some features of the spatial structure of community diversity in mountainous areas are revealed.

Keywords: biodiversity, altitudinal zonation, orobiome, mapping, the Abrau Peninsula, Sub-Mediterranean.

GEOINFORMATION ANALYSIS OF DESERTIFICATION IN NORTH-WESTERN PRECASPIAN REGION

Arid Ecosystems

Kulik K.N.,  Petrov V.I.,  Yuferev V.G.,  Tkachenko N.A.,  Shinkarenko S.S. GEOINFORMATION ANALYSIS OF DESERTIFICATION IN NORTH-WESTERN PRECASPIAN REGION // Arid ecosystems. 2020. V. 26. № 2 (83). P. 16-24. | PDF

An analysis of the desertification of the North-Western Precaspian region using geo-information technologies and aerospace data to identify changes in the area of hotspots of desertification showed that the area of degraded and deserted lands increases with the growth in the quantity of sheep and goats. With a relatively stable number of animals, the role of climatic factors increases, which leads to an increase in the speed and amplitude of changes in the area of hotspots of desertification, both in the direction of decrease, with sufficient moisture, and an increase in dry years. Landscape fires have a significant impact, which lead not only to a decrease in the projective cover, but also to the depletion of the species composition of vegetation. The study and mapping of the relief made it possible to establish spatially determined geomorphological features of the territory as a factor affecting local moisture, and, accordingly, on the stability of ecosystems and the possibility of phytomelioration.

Keywords: geographic information systems, analysis, desertification, degradation, mapping, modeling, satellite imagery, hotspots, area, correlation, regression, phytomelioration.
