图3 大金山岛3种植被类型土壤细菌类群相关性网络。任意两点连线说明可操作分类单元(OTU)之间相关性显著(p < 0.05), 红色代表显著正相关, 蓝色代表显著负相关。DF, 落叶阔叶林; DS, 落叶灌丛; EF, 常绿阔叶林。d, 网络直径; D, 密度; l, 路径长度; n, 节点数。

Fig. 3 Correlation networks of soil bacteria across three vegetation types in Dajinshan Island, Shanghai. The connection between any two points indicates that the correlation between operational taxonomic units (OTUs) is significant (p < 0.05). Red represents positive correlation, while blue represents negative correlation. DF, deciduous broadleaf forest; DS, deciduous shrubland; EF, evergreen broadleaf forest. d, network diameter; D, density; l, path length; n, number of nodes.
