土壤微生物在高山森林生态系统许多能量流动和物质循环过程中具有重要意义。土壤微生物群落沿着海拔梯度的分布格局是青藏高原重要的研究课题。然而，我们的理解土壤微生物群落和关键因素之间的联系，沿沿着海拔梯度的不同斜坡仍然有限。在这里，细菌和真菌群落的多样性，组成和相互作用以及对环境因素的响应在塞格里拉山东西坡的五个海拔地点（3,500米，3,700米，3,900米，4,100米，4,300米）进行了比较，通过使用Illumina MiSeq测序。结果表明，不同海拔高度土壤微生物群落组成和多样性差异较大，主要受土壤全氮和碳酸盐的影响。结构方程模型表明，海拔对土壤微生物群落的影响大于坡度。共现网络分析表明，在细菌和真菌群落的相互作用中，真菌是稳定的，而细菌的贡献更大。子囊菌门是微生物群落内部相互作用的关键枢纽，可能影响青藏高原高山森林生态系统土壤微生物共生网络的恢复力。
Soil microbes are of great significance to many energy flow and material circulation processes in alpine forest ecosystems. The distribution pattern of soil microbial community along altitudinal gradients is an essential research topic for the Tibetan Plateau. Yet our understanding of linkages between soil microbial communities and key factors along an altitudinal gradient of different slopes remains limited. Here, the diversity, composition and interaction of bacterial and fungal communities and in response to environmental factors were compared across five elevation sites (3,500 m, 3,700 m, 3,900 m, 4,100 m, 4,300 m) on the eastern and western slopes of Mount Segrila, by using Illumina MiSeq sequencing. Our results showed that microbial community composition and diversity were distinct at different elevations, being mainly influenced by soil total nitrogen and carbonate. Structural equation models indicated that elevation had a greater influence than slope upon the soil microbial community. Co-occurrence network analysis suggested that fungi were stable but bacteria contributed more to among interactions of bacterial and fungal communities. Ascomycota was identified as a key hub for the internal interactions of microbial community, which might affect the soil microbial co-occurrence network resilience of alpine forest ecosystems on the Tibetan Plateau.
