图3. 2014-2016年不同载畜率下生态系统碳交换的变化(平均值±标准误差)。CK, 对照; LG, 轻度放牧; HG, 重度放牧。大写字母表示同年内不同载畜率差异显著(p < 0.05), 小写字母表示同一载畜率在不同年份间差异显著(p < 0.05)。相同字母表示无显著差异(p > 0.05)。
Fig. 3. Variations of ecosystem carbon exchange in plots with different stocking rates from 2014 to 2016 (mean ± SE). CK, no grazing control; LG, lightly grazing; HG, heavily grazing. Capital letters indicate significant differences (p < 0.05) in sites with different stocking rates in the same year. Lowercase letters indicate significant differences (p < 0.05) in different years at sites with the same rate of stocking. The same letters mean no significant difference (p > 0.05).
