图3 不同灌木林地土壤微生物物种多样性(a)和谱系多样性(b)。不同的字母表示样地间存在显著差异(P < 0.05), 数据为平均值 ± 标准误差。Aro: 黑沙蒿林地; Sap: 北沙柳林地; Cam: 柠条锦鸡儿林地; PD: 系统发育多样性; NRI: 净种间亲缘关系指数; NTI: 净最近种间亲缘关系指数。

Fig. 3 Soil microbial species diversity (a) and phylogenetic diversity (b) in different shrublands. Different lowercase letters indicate significant differences (P < 0.05), data are shown as mean values ± SE. Aro, Artemisia ordosica shrubland; Sap, Salix psammophila shrubland; Cam, Caragana korshinskii shrubland. PD, Faith’s phylogenetic diversity index; NRI, Net relatedness index; NTI, Net nearest taxa index.
