图3. 泥炭藓沼泽湿地CH4排放通量季节变化(平均值±标准误)。B, 裸露样地; P, 金发藓覆被样地; S, 泥炭藓覆被样地。不同大写字母表示同一覆被类型不同季节差异极显著(p < 0.01); 不同小写字母表示不同覆被类型间差异显著(p < 0.05)。*表示同一季节不同覆被类型差异显著(p < 0.05); **表示同一季节不同覆被类型差异极显著(p < 0.01)。 |
Fig. 3. Seasonal changes in methane emission fluxes in the Sphagnum bog (mean ± SE). B, bare land plot; P, Polytrichum commune plot; S, Sphagnum paluster plot. Different uppercase letters indicate significant difference among the same cover type in different seasons (p < 0.01); different lowercase letters indicate significant difference among the annual methane emissions of three cover types (p < 0.05). * represents a significant difference among the three cover types at the same season (p < 0.05); ** represents a significant difference among the three cover types at the same season (p < 0.01). |
