Phases of warm and cool, humid and arid climates were alternated cyclically. The average duration of the phase is 400-600 years. The biggest gradients of landscape and climate changes were in the early Holocene (13-8 thousand years ago), the Subboreal period (4.2-2.7 thousand years ago), and at the end of the Holocene (from 1200 years ago). The smallest gradients were at the optimum of the modern interglacial (8-5,500 years ago). The change of phases occurred approximately synchronously in the Forest Steppe and Steppe, which indicates that they reflect a global climate signal, but the gradients of changes between phases were different in different zones – they are smaller in terms of moisture and greater in terms of heat supply in the Steppe, than in the Forest-Steppe. The gradients increased to the east and south in both zones, which reflects the greater stability of landscapes of the western physiographic provinces of Ukraine. There was a direct ratio between heat and moisture supply up to 5,500 years ago (that is, an increase in temperature leads to an increase in humidity), and after this time point it was mostly inverse ratio. A direct correlation between development indicators of the soil and geochemical processes and changes in vegetation as indicators of climate changes was established.
