图3. 中国亚热带喀斯特山地灌草丛不同放牧强度下的群落高度、盖度和地上生物量变化(平均值±标准误)。CK, 无放牧; HG, 重度放牧; LG, 轻度放牧; MG, 中度放牧。不同小写字母表明不同放牧强度间差异显著(p < 0.05)。
Fig. 3. Changes of community height, coverage and aboveground biomass of shrub tussock under different grazing intensities in subtropical karst mountains of China (mean ± SE). CK, none grazing; HG, heavy grazing; LG, light grazing; MG, moderate grazing. Different lowercase letters show significant difference between different grazing intensities (p < 0.05).
