Nonmetric multidimensional scaling ordination (NMDS) of soil bacterial communities based on genus level across two horizons and three forest types (a) at Tiantangzhai and (b) Yaoluoping Nature Reserve based on the average Bray–Curtis dissimilarity matrix. The difference of bacterial community composition across different groups are analyzed (c) at Tiantangzhai and (d) Yaoluoping Nature Reserve. Yellow represents bacterial groups with no significant differences (e) at Tiantangzhai and (f) Yaoluoping Nature Reserve.
