The elementary soil areas of the Mykolaiv-Horodok Opillia

Abstract

During the investigation of soil structure of Mykoliv-Horodok Opillia we used the methods of detection (natural-cartometric, relief sculpture, quality-genetic) and interpretation (statistical cartometric, functional and analytical) of the soil structure. To characterize elementary soil areas of the key area the natural-cartometric method was used, it makes it possible to determine the parameters of the soil structure and obtain quantitative indicators for the key elementary soil areas (ESA) parameters, which are elementary soil areas composition and area ratio, complexity, fractionality, breakdown, heterogeneity and contrast range. The article presents results of a study of qualitative and quantitative characteristics of elementary soil areas of the Mykolaiv-Horodok Opillia. The degree of variability of ESA areas was identified and analysed with coefficient of the differentiation of the soil outlines and methods of variation statistics. Form, degree of tortuosity and elongation of area limits using the coefficient of the dismemberment were studied. The character of outlines of elementary soil areas within the area of research was investigated. The basic features of ESA borders depending on various environmental factors are identified. Certain laws of changing of the basic parameters of elementary soil areas, which form the soil structure of Mykolaiv-Horodok Opillia were traced. Key words: elementary soil area, structure of the soil cover, coefficient of variability of soil outlines, coefficient of the differentiation of the soil outlines, coefficient of the dismemberment of the soil boundaries.
