- Аннотация: In 1998–2010, we identified a clear trend of increasing mean annual air temperature, which, against the background of decreasing annual precipitation, was expressed in the trengthening of aridity in southern Moscow region. The discovered climatic trends caused coupled trends of a decrease in the emission component of the carbon cycle in both natural and agricultural ecosystems as a result of inhibition of the decomposition of soil organic matter and litter caused by an acute shortage of water during droughts. The probability of the discovered trends of soil respiration and response of its value to extreme weather phe nomena mainly depended on the water retention capacity of soils, which is determined by their texture of soils and land use. We may assume that the ecosystems most tolerant to the observed and expected climatic changes in terms of soil respiration will be natural ones formed in loamy soils. Strengthening of aridity of climate and extreme weather phenomena expressed both as the acute shortage of precipitation and as their abundance are most likely to have a significant depressive effect on respiration of both light sandy soil and loamy soils used in agriculture.
