Зміни клімату і проблеми дегуміфікації чорноземів типових Лівобережного Лісостепу України

Abstract

A study of changes in the climatic conditions of the Left-Bank Forest-Steppe of Ukraine, which occurred over the past fifty years (1973-2022), was carried out. Analysis of the dynamics of average annual air temperatures in the research area shows that over a fifty-year observation period, the average air temperature clearly increases. If at the beginning of observations it averaged about 6.5 °C, then at the end of the study (more than 9.4 °C (trend line), that is, the temperature increase is 2.9 °C. Fluctuations over the years amounted to 4.7 °C (1987). ( 10.2 °C (2020). A similar trend is observed according to the dynamics of the average annual air temperature during the growing season. However, the minimum air temperatures (14.0-14.1°C) were observed in 1976, 1978 and 1987, while the maximum temperatures (18.6-19.2°C) were observed in the last period of research (2010, 2012, 2018). Analysis of data on average annual temperatures for the study period (1973-2022) shows that the air temperature during the growing season increased by almost 3°C. The analysis of scientific literature and our observations indicate a certain aridization of the climate of the Forest-Steppe of Ukraine
