图7. 不同干扰强度下松山油松林土壤微生物群落组成(门水平)与环境因子的冗余分析(RDA)。
A, 土壤真菌。B, 土壤细菌。LD, 低干扰区; HD, 高干扰区; ND, 无干扰区。AK, 速效钾含量; HC, 草本盖度; LC, 凋落物盖度; Tree_DBH, 乔木胸径; SWC, 土壤含水量。黑色箭头实线越长, 影响越大。
Fig. 7. Redundancy analysis (RDA) between soil microbial communities (phylum level) and environmental factor in different disturbance intensity groups in Songshan Pinus tabuliformis forest.
A, Soil fungi. B, Soil bacteria. LD, low disturbance group; HD, high disturbance group; ND, no disturbance group. AK, available potassium content; HC, herb cover; LC, litter cover; Tree_DBH, tree diameter at breast height; SWC, soil water content. The longer the solid black arrow line, the greater the influence.
