【目的】

揭示祁连山祁连圆柏天然林土壤真菌群落的海拔分布格局及其驱动因素，为祁连山生态环境保护提供土壤微生物学领域的理论依据与科学支撑。

【方法】

以祁连山地区不同海拔梯度的祁连圆柏天然林为研究对象，运用高通量测序技术对其土壤中的真菌多样性及群落组成进行测定与分析，并进一步探讨影响真菌群落结构的主要因素。

【结果】

不同海拔高度土壤真菌共有6门、27纲、81目、170科、295属、355种。在门水平分类中，担子菌门Basidiomycota与子囊菌门Ascomycota占据主导地位，成为优势类群，相对丰度分别为0.22~0.66和0.11~0.39。在属水平上，湿伞属Hygrocybe和被孢霉属Mortierella是土壤中的优势真菌。不同海拔间土壤真菌多样性存在显著差异（P<0.05），中、低海拔土壤真菌群落丰富度和多样性显著高于高海拔土壤；土壤真菌群落多样性总体随着海拔升高呈先增大后降低的变化趋势。冗余分析和Spearman分析结果表明，海拔、土壤pH值、SOM、TP、AK和AP是影响土壤真菌群落结构变化及多样性分布格局的关键环境因子。

【结论】

祁连山祁连圆柏天然林土壤真菌群落组成丰富，以担子菌门、子囊菌门为优势类群，土壤pH值、AP、TP为驱动土壤真菌群落结构的核心变量，且真菌多样性与海拔、HN呈负相关，与AK和SOM呈正相关。

【Objective】

To reveal the altitudinal distribution pattern and driving factors of soil fungal communities in Sabina przewalskii natural forests, thereby providing a theoretical basis and scientific support in the field of soil microbiology for the ecological protection of the Qilian mountains.

【Method】

Focusing on the Sabina przewalskii natural forests soil at different altitudes in Qilian mountains, the high-throughput sequencing technology was used to analyze the diversity and community composition of soil fungi and explore the main factors influencing the soil fungal community structure.

【Result】

A total of 6 phyla, 27 classes, 81 orders, 170 families, 295 genera and 355 species of soil fungi were discovered across different altitudes at the phylum level, Basidiomycota and Ascomycota dominated the fungal communities, with relative abundances of 0.22-0.66 and 0.11-0.39. Hygrocybe and Mortierella were the dominant genera. There were significant differences in soil fungal among different altitudes (P<0.05), with the richness and diversity of soil fungal communities at low and medium altitudes being significantly higher than those at high altitudes. Overall, the soil fungal diversity first increased and then decreased with increasing altitude. Redundancy analysis (RDA) and Spearman correlation analysis showed that altitude, soil pH, SOM, TP, AK and AP were the key environmental factors affecting the community structure and diversity distribution pattern of soil fungal.

【Conclusion】

The soil fungal community in Sabina przewalskii natural forests of the Qilian mountains is rich in composition, with Basidiomycota and Ascomycota as the dominant phyla. Soil pH, AP and TP are the core variables driving the soil fungal community structure. In addition, fungal diversity is negatively correlated with altitude and HN, while positively correlated with AK and SOM.
