With Li-8100 chamber, the soil respiration rates in different succession stages of Larix gmelinii plantation in Great Xing’ an Mountains was measured from June to October, 2014. Results show that the variations of soil respiration can be expressed as a one-humped curve. The maximum of soil respiration rate occurs from July for early and mid-succession stage to August for late succession. Soil respiration rate varies from 1.2 to 4.6μmol ۬∙m-2∙s-1 with mean value of 2.76μmol ∙m-2∙s-1 for early succession, 1.5 to 5.6μmol ∙m-2∙s-1 with mean value of 3.17μmol ∙m-2∙s-1 for mid-succession, and 1.8 to 4.1μmol ∙m-2∙s-1 with mean value of 2.89μmol ∙m-2∙s-1 for late succession. Soil temperature is the main factor to affect soil respiration and there is a significant correlation between soil respiration and the soil temperature at 10cm depth in all different succession forests, but less correlation is observed between soil respiration and soil water content.
