To understand the fluxes of soil greenhouse gases from Alpine meadows on the Qinghai-Tibet plateau during non-growing season, a static chamber method was used to sample gases of soil CO_2, CH_4 and N_2O from alpine meadow on the plateau of Southern Qinghai province during snow cover period, and gas chromatography was used to analyze concentrations of these gases. The results showed that soil CO_2 flux was 1.33 g?(m~2?h)~(-1), soil CH_4 flux was -0.19 mg?(m~2?h)~(-1), and soil N_2O flux was 0.21 mg?(m~2?h)~(-1) when the snow depth was 9-10 cm on March 3 and 4 during the prevalence period of snow cover; soil CO_2 flux was 4.70 g?(m~2?h)~(-1),and soil N_2O flux was 0.24 mg?(m~2?h)~(-1), and soil CH_4 flux was -1.23 mg?(m~2?h)~(-1) when the snow depth was 8-9 cm on April 30 during the end period of snow cover. And soil CO_2 and N_2O fluxes were low or negative, soil CH_4 flux was negative and its absolute value was low when the snow depth was less than 4 cm during snow cover period. In addition, soil CO_2 or N_2O flux was positively correlated with the snow depth, and soil CH_4 flux was negatively correlated with the snow depth (P<0.05). Additionally, soil CO_2 or N_2O flux was negatively correlated with CH_4 fluxes, and soil CO_2 was positively correlated with soil N_2O flux. In addition, soil CO_2 flux was the highest during the growing season, followed by the end period of snow cover, and it was the lowest during the prevalence period of snow cover; soil N_2O flux was high during the growing season, followed by the end period of snow cover, and it was the lowest during the prevalence period of snow cover; soil CH_4 flux was negative, and its absolute value was higher during the growing season than other seasons, and it was the lowest during the prevalence period of snow cover. The results suggested that the change in snow cover would influence the fluxes of soil greenhouse gases from alpine meadow on the Qinghai-Tibet plateau.
