图3 细菌(A)和线虫(B) alpha多样性(Shannon index)对凋落物多样性的响应。误差线表示标准差(n = 10), 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; 1Species: 只添加绒毛猴欢喜凋落物; 2Species: 添加绒毛猴欢喜 + 华马钱; 4Species: 添加绒毛猴欢喜 + 华马钱 + 蚁花 + 番龙眼; 7species: 添加绒毛猴欢喜 + 华马钱 + 蚁花 + 番龙眼 + 黄葛树 + 羊乳榕 + 印度锥。

Fig. 3 Response of bacterial (A) and nematode (B) alpha diversity (Shannon index) to the litter diversity. Error bar indicate standard deviation (n = 10), and different lowercase letters indicate significant differences between treatments (P < 0.05, Duncan’s test). CK, Control treatment; 1Species, The addition of Sloanea tomentosa; 2Species, The addition of Sloanea tomentosa and Strychnos cathayensis; 4Species, The addition of Sloanea tomentosa, Strychnos cathayensis, Orophea laui and Pometia pinnata; 7Species, The addition of Sloanea tomentosa, Strychnos cathayensis, Orophea laui, Pometia pinnata, Ficus virens, F. sagittata and Castanopsis indica.
