图1 细菌(A)和线虫(B) alpha多样性(Shannon index)对单独添加不同植物凋落物的响应。误差线表示标准差(n = 8), 不同小写字母表示处理间差异显著性(P < 0.05, 邓肯检验)。CK: 对照处理。PC: 望天树; ST: 绒毛猴欢喜; SC: 华马钱; OL: 蚁花; PP: 番龙眼; FV: 黄葛树; FS: 羊乳榕; CI: 印度锥。

Fig. 1 Response of bacterial (A) and nematode (B) alpha diversity (Shannon index) to the litter addition of different plant species. Error bar indicate standard deviation (n = 8), and different lowercase letters indicate significant differences between treatments (P < 0.05, Duncan’s test). CK: Control treatment; PC, Parashorea chinensis; ST, Sloanea tomentosa; SC, Strychnos cathayensis; OL, Orophea laui; PP, Pometia pinnata; FV, Ficus virens; FS, F. sagittata; CI, Castanopsis indica.
