图1 刈割和施肥对物种多样性的影响(平均值±标准误差, n = 36)。 NH, 不刈割; H3, 中度刈割; H1, 重度刈割。相同的大写字母表示不施肥样方中刈割处理间无显著差异(p > 0.05); 相同的小写字母表示施肥样方中刈割处理间无显著差异(p > 0.05); **, p < 0.01。

Fig. 1 Effects of clipping and fertilizing on species diversity (mean ± SE, n = 36). NH, unclipped; H3, stubbled 3 cm; H1, stubbled 1 cm. Same capital letters indicate no significant difference among clipping treatments in unfertilized quadrat (p < 0.05). Same small letters indicate no significant difference among clipping treatments in fertilized quadrat (p < 0.05); **, p < 0.01.
