- Аннотация: The values of heterotrophic (HR) and total soil respiration for the Entic Carbic Podzol under a coniferous–broadleaved forest in the south of Moscow oblast (54.89° N, 37.56° E) calculated using the Romul_Hum model and a new version of the EFIMOD3 system of models are reported. The results of soil respiration modeling correlate well with the field measurement data. The Romul_Hum model better simulates the HR intensity of the studied soil in wet years as compared with dry years, when it somewhat overestimates the HR values. The spatially explicit modeling of HR and root respiration using EFIMOD3 takes into account the variation of carbon pools and fluxes associated with the distribution of the plant litterfall and hydrothermal conditions under the forest canopy. The results show that the HR intensity differs approximately twofold in early and middle growing season, and the HR values in individual parts of the simulation site at the same dates differ more than 3.5-fold. The spatial and temporal variation of soil respiration influences the accuracy of estimates for the carbon budget in forest ecosystems. The used models are efficient tools for analyzing the changes in carbon stocks and soil respiration and estimating carbon sink in forest ecosystems, including the tasks related to forest management.
