Abstract

Permafrost thaws accelerate the rates of carbon released by the soil into the atmosphere and cause significant positive climate-change feedback. We selected Munkhkhairkhan mountain as the study area. The main purpose of this study is to estimate GHG emissions and to calculate the emission factor (EF) at the study sites in Doloon Nuur and Shuurkhai in Munkhkhairkhan. This study is conducted in summer 2022 and carbon dioxide (CO2) emissions were measured using the EGM-4 instrument. Soil samples were collected at depths of 0-5 cm, 5-10 cm, and 10-15 cm at the sites. We have determined the soil organic carbon content (SOC) at peat and nonpeat in both sites. According to the results, CO2 fluxes ranged between 0.1 and 18.5 µmol/m-2 s-1 in the Doloon Nuur and Shuurkhai. Furthermore, EF at all sites on Munkhkhairkhan mountain (±standard error) was 112.3 g [CO2] m-2 yr-1 (±18.2), 5.9 g [CH4] m-2 yr-1 (±1.0). SOC content was 10.5% in 0-5 cm, 14.2% in 5-10 cm, and 11.4% in 10-15 cm at the study sites in Shuurkhai. The SOC content at the sites in Doloon Nuur ranges from 3.1% in 0-5 cm, 2.3% in 10-15 cm and 1.7% in 10-15 cm. This study is conducted with a year measurement; therefore, further research should extend the time period and can be used as a baseline study.
