| Popis: | The chernozems evolution of the Carpatho-Danubian-Pontic space clearly shows two consecutive phases: climatogenic and anthropo-climatogenic. The latter is characterized by increasing agrogenic impact on soil climate. The soil cover of Carpathian-Danubian-Pontic space is the hierarchical functional system long-time product. Pedogenetic factors → pedogenetic regimes → pedogenetic processes → soil (soil cover). During Pleistocene, the chernozem pathogenesis in the region resumed 13 times, each time starting from the carbonic chernozem phase. Zonal climatic cyclicality has led to the differentiation of chernozem subtypes, determined by the zonal differentiation of pedogenic regimes and typogenetic elemental processes. The current stage of chernozem cleavage in the region began 10-12 thousand years ago. The evolution of soils in the soil was determined by the climate cyclicality and the increase of anthropogenic imputations and involves the succession over time of several phases: - Cryogenic with poorly developed soil by A (AO) - C Order; - Early dynamic halocene with developed zonal soil formation; - Late halocene with climatic evolution of the profile; - Natural-anthropogenic. During the last one, four eras were accelerated: natural-anthropo-turbian, naturalanthropic modification, natural-anthropic restructuring and natural-anthropic stagnation. Increasing the anthropogenic impulses led to the modification of the climatic → soil relations in the sense of increasing the degree of continentalisation of the soil climate materialized in the aridization of the soil cover, the change of the sense and intensity of the typogenic processes and the induction of some nontypical elementary processes of the chernozemic pedogenesis. |
