%X The value order of carbon dioxide emission from different land use of alpine meadow was significantly with season changing.It was found that the Potentilla fruticosa shrub meadow(C,1871.40g/m2)> Kobresia humilis meadow(A,1769.63g/m2)>Degraded Potentilla fruticosa shrub meadow(D,1495.60g/m2)>Degraded Kobresia humilis meadow(B,1191.26g/m2) during growth season,A(661.46g/m2)>C(550.90g/m2)>B(502.50g/m2)>D(384.50g/m2) in rest period;and A(2431.09g/m2)>C(2422.30g/m2)>D(1880.10g/m2)>B(1694.06g/m2) for whole year,separately.This deference not only decided the soil microbial activity and soil characters,but also have the closely relationship to shortage of frozen period.
