title: [Values of carbon dioxide emission from different land-use patterns of alpine meadow].
abstract: 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, 1871.40 g/m2) > Kobresia humilis meadow(A, 1769.63 g/m2) > Degraded Potentilla fruticosa shrub meadow(D, 1495.60 g/m2) > Degraded Kobresia humilis meadow(B, 1191.26 g/m2) during growth season, A(661.46 g/m2) > C(550.90 g/m2) > B(502.50 g/m2) > D (384.50 g/m2) in rest period; and A(2431.09 g/m2) > C(2422.30 g/m2) > D(1880.10 g/m2) > B(1694.06 g/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.
