title: Geoinformation Analysis of Chernozem Diversity and Protection in Russia
abstract: The areal and typological representativeness of chernozem soil diversity throughout Russia and within federal-level specially protected natural areas (SPNAs) was assessed based on geoinformation analysis using a vector soil map of Russia at a scale 1 : 2 500 000 (the combined version of the Soil Map of the RSFSR and Soil Map of Crimea). All chernozem soils cover 123.5 million ha (7.4% of the country’s soil cover), of which 86.4% are actually chernozems and 12.3, 0.8, and 0.5% are chernozem-meado
