图1. 基于Bray-Curtis相异性指数, 黄帚橐吾根围土壤微生物碳源代谢结构的非度量多维尺度排序图(NMDS)。图上仅显示与土壤微生物碳源代谢结构显著相关的变量(p ≤ 0.05)。椭圆代表平行样品间的标准偏差。Control, 对照斑块; LD, 低密度斑块; MD, 中密度斑块; HD, 高密度斑块。AWCD,平均颜色变化率。
Fig. 1. Nonmetric multidimensional scaling (NMDS) ordination patterns of carbon resources utilization of soil microbial community lived in the rhizosphere of Ligularia virgaurea based on Bray-Curtis dissimilarity. Only some significant vectors (r2-values and p-values were shown on the right panels) at the 95% confidence level were displayed onto the NMDS ordination plots. Ellipses represent standard deviation among parallel samples. Control, control patch; LD, low density patch; MD, moderate density patch; HD, high density patch. AWCD, average well color development.
