图2. 大气温度和不同处理的凋落物层温度动态(平均值, n = 3)。A, 大气温度和对照(CK)中凋落物层温度。B, 增雪处理(SA)和除雪处理(SR)与对照相比的凋落物层的温差。正值代表处理后温度升高, 负值代表处理后温度降低。
Fig. 2. Dynamics in air temperature and the temperatures at the litter layer in different treatment plots (mean, n = 3). A, average air temperature and temperature at the litter layer under the control (CK). B, difference in the temperature between the snow-addition (SA) or snow-removal treatment (SR) and the control. Positive value indicates increased temperature after the treatment, while negative value indicates decreased temperature after the treatment.
