图3 土壤细菌优势菌(门水平)与环境因子间的相关性(Mantel检验)
注:Mantel检验用于评估微生物群落组成(基于Bray-Curtis距离)与环境因子矩阵(基于欧氏距离)之间的相关性。不同采样点土壤细菌群落组成与土壤环境因子的相关强度(Mantel's r)由其连接曲线的粗细表示。显著性水平(Mantel's P)以双尾检验进行评估:P<0.01表示极显著相关,0.01<P≤0.05表示显著相关,P>0.05表示无显著相关。BD:土壤容重;SWC:土壤含水率;pH:土壤酸碱性;EC:土壤电导率;SOC:土壤有机碳;TN:土壤全氮;TP:土壤全磷;TK:土壤全钾。放线菌门:Actinobacteriota;变形菌门:Proteobacteria;芽单胞菌门:Gemmatimonadota;拟杆菌门:Bacteroidota;绿弯菌门:Chloroflexi
