图2. 北京松山自然保护区不同干扰强度下土壤微生物群落主坐标分析(PCoA)。
A, 土壤真菌。B, 土壤细菌。点越近, 圈越小, 微生物组成越相似。置信区间水平为0.85。LD, 低干扰区; HD, 高干扰区; ND, 无干扰区。
Fig. 2. Principal co-ordinates analysis (PCoA) of soil microbial communities in different disturbance intensity groups in Beijing Songshan Nature Reserve.
A, Soil fungi. B, Soil bacteria. Closer distances between dots and smaller circles represent higher similarity in microbial composition. The confidence interval level is 0.85. LD, low disturbance group; HD, high disturbance group; ND, no disturbance group.
