Spatial distribution of plant phytocomplexes on the hilly-ridge sandy territories of the Don basin

Abstract

The aim of the research was to establish spatial patterns of placement of the most productive areas of pasture phytocenoses and to assess biodiversity on the sandy massifs of the Don basin. The objects of research are herbaceous plant communities on geomorphologically different sections of the Ilovlinsky sand massif. Methods of mathematical statistics of the MATLAB package and the SURFER program were used to process and analyze the results. Regression analysis was carried out by the generalized linear regression method. The dependence of the yield of pasture grasses on the projective cover is determined. The results of a statistical regression model describing this relationship in the form of a logistic function are presented. The features of the ecosystem of plant communities on open and medium-grown sands are revealed.
