Abstract:
A comparative analysis of the spatial-temporal trends in the emission of CO₂from soils of different functional zones of the city of Kursk, a dark gray soil of an oak forest, and a typical steppe chernozem has been performed. The averaged CO₂emission from the urban soils is 25% higher than that from the natural soils (32.1 ± 17.8 and 17.8 ± 10.2 g CO₂/m²daily, respectively). The spatial heterogeneity of the CO₂emission is also significantly higher for the urban soils, while variation in temporal dynamics of soil respiration among the studied ecosystems was insignificant.
