To investigate the potential impact of climate warming on soil carbon emissions from Quercus mongolica forest, the response of soil respiration components to a 1℃ temperature increase and root-cutting interaction during the period from May to November was examined in a secondary forest dominated by Quercus mongolica in the Sanjiang Plain. he findings demonstrate that the average increase in surface soil temperature was 1.35℃ in the unbroken root group and 0.65℃ in the broken root group, while the average increase in surface soil water content was 0.02m₃ ?m^_-3 (P<0.05). Additionally, there was an 11.9% increase in soil total respiration rate (P<0.05), with no significant changes observed in soil heterotrophic respiration (P>0.05). The proportion of soil heterotrophic respiration rate to total soil respiration rate exceeded 50% in all groups during each month. The soil temperature exhibited a significant positive correlation with both the total respiration rate and heterotrophic respiration rate of the soil (P<0.01), while the soil volume water content exhibited a significant negative correlation with both the soil total respiration rate and the soil heterotrophic respiration rate (P<0.01). The increase in temperature led to a reduction in the sensitivity of soil respiration(Q₁₀), with the Q₁₀ value of total soil respiration decreasing by 0.45 and the Q₁₀ value of heterotrophic soil respiration decreasing by 0.39. Q₁₀ exhibited temporal variations, with the highest values observed in September, followed by August and October, while the lowest values were recorded in November. The two-way ANOVA revealed a significant main effect for temperature increase and root breaking as independent variables (P<0.05). However, no significant interaction between them was observed (P>0.05). [Conclusion]During the initial phase of simulated climate warming, there was a 11.9% increase in total soil respiration rate in Quercus mongolica forest in average, leading to an amplified emission of soil carbon and further exacerbating climate change. Seasonal variations were observed in the magnitude of this increase, with higher soil carbon emissions occurring during summer months and greater sensitivity to changes in temperature during the transition from summer to autumn.
