Abies fabri forest is one of representative type of subalpine dark coniferous forest in Southwest China. The difference was obvious among CO₂ emissions from soils in Abies fabri forest region on the east slope of Gongga Mountain. The soil respiration of clearcut site approached 5.89 μmol/hm²s CO₂. The series of soil respiration was arranged: September>August>June>July>May>October>November. The soil respiration of Abies fabri forest approached 5.76μmol/hm²s CO₂. The series of soil respiration was arranged: August>July>September>June>May>October> November. The soil respiration of succession forest approached 3.26, mol/hm²s CO₂. The series of soil respiration was arranged: May>July> August>June> September>October>November. There existed a good linear correlation between soil respiration of cleareut site-succession forests and near surface-surface temperature. There existed a good linear correlation between soil respiration of Abies fabri forest and 5cm-10cm soil temperature. The soil CO₂ flux of clearcut site was 223.91kg/hm²d. The soil CO₂ flux of succession forest was 123.76kg/hm²d. The soil CO₂ flux of Abies fabri forest was 218.48kg/hm²d.
