Abstract: To investigate the effects of soil temperature and moisture on soil respiration rate of different land use types in the extreme arid ecological migration area, and to provide scientific support for accurately revealing the carbon cycle characteristics of different land use types in the study area. Soil respiration rate, soil temperature, and soil moisture content were measured in mid-May, June, and July 2023 using the LI-8100 soil carbon flux measurement system and soil moisture monitor, dividing the study area into four land use types: Wild grassland, Caragana forest, original landform, and Cultivated land. The results showed that.（1） the overall soil respiration rate was as follows: Cultivated land ＞ Wild grassland ＞ Caragana forest ＞ Original landscape. Soil respiration rates of different land use types were significantly positively correlated with temperature before reaching the optimum temperature（P＜0.05）, and exceeding the optimum temperature would reduce soil respiration rates.（2） The soil respiration rates of different land use types were well fitted to the exponential model with the soil temperature at 5 cm depth, with Q10 values ranging from 3.18 to 4.66, and the correlation between soil respiration rates and the soil temperature at 10 cm depth was significant（P＜0.05） in the original landform and Cultivated land.（3） The linear correlation between soil respiration rate and soil moisture content（10 cm） was not significant（P＞0.05）, and the interaction between soil temperature（5 cm） and soil moisture content（10cm） was significantly correlated（P＜0.05） for the three land-use types except Cultivated land. Different land use types have significant effects on CO2 emissions in extreme arid ecological Immigration area, and soil temperature and moisture together are the main factors in the variation of soil respiration rates. The development of rational land-use policies that take into account the regional climate can further help to achieve the “dual-carbon goal”, with a view to providing a theoretical basis for land-use master planning in ecological migrant zones with extreme aridity.
