The dynamic changes of soil organic matter (SOM) in alpine ecosystems were investigated using lignin as a molecular marker. Soils from a swamp meadow (WQZ) and a subalpine meadow (AMX) in Hongyuan County, on the northwestern Sichuan Plateau, were analyzed to examine the vertical distribution, degradation state, and environmental drivers of lignin within the soil profile. The results indicated that: In AMX, soil pH was observed to increase with depth, while water content remained low. Both SOM and lignin contents were found to decrease with depth, and soil texture exhibited clear vertical variation. In contrast, WQZ soils showed minimal inter-layer pH variation and high water content ((3times that of AMX). Affected by seasonal waterlogging, SOM and lignin in WQZ initially decreased and then increased with depth. All WQZ profiles were identified as clay loam, with fine particle content exceeding 90%. High lignin content in the AMX surface layer was attributed to root input and declined markedly with depth. In WQZ, long-term flooding was associated with lignin accumulation in deeper layers via leaching or bioturbation, resulting in higher relative lignin contribution to SOM at depth compared to surface layers. Ratios of guaiacyl (Ad/Al)v and syringyl (Ad/Al)s monomers in both soil types exceeded 0.6across all layers, indicating significant oxidative degradation of lignin side chains, which intensified with depth. Demethylation/methoxylation degradation was more pronounced in AMX than in WQZ. Lignin stability was regulated by soil texture: absolute lignin content (Σ8) was higher in clay silt, while sand content was positively correlated with the lignin contribution to SOM (Λ8) within the same layer. Prokaryotic and eukaryotic abundances were influenced by soil water content and pH. Proteobacteria dominated the surface layer of AMX, whereas Acidobacteria were more abundant in deeper layers. In WQZ, Chloroflexi were enriched with depth, and basidiomycete abundance was significantly higher in AMX than in WQZ.

以川西北高原红原县沼泽(WQZ)与亚高山草甸(AMX)土壤为对象,通过分析土壤剖面木质素分布、降解特征及环境因子互作机制,揭示SOM来源、转化过程及其对环境的影响.结果表明:AMX土壤pH值随深度升高,含水率较低,SOM和木质素含量随深度减少,且土壤质地呈现明显的垂向变化;WQZ土壤pH值层间差异小,含水率高((AMX的3倍),其SOM与木质素分布受季节性积水影响呈现先降后升趋势,其剖面均为黏壤土,细粒含量超过90%.两地SOM均源于被子草本维管植物. AMX表层高木质素含量与根系输入相关,并随深度显著减少;WQZ因长期淹水,木质素通过淋溶或生物扰动在深层积累,其相对有机质含量高于表层.AMX和WQZ土壤各层的愈创木基类单体酸醛比(Ad/Al)v与紫丁香基类单体酸醛比(Ad/Al)s值均大于0.6,表明木质素侧链经历了显著的氧化降解,并随土壤剖面加深而增强.与WQZ相比AMX土壤的去甲基/甲氧基降解作用更为强烈.土壤质地调控木质素稳定性,黏粉粒中木质素绝对含量(Σ8)较高,而砂粒与木质素相对同层土壤有机质的含量(Λ8)呈正相关,大粒径土壤物理屏障延缓木质素分解.环境因子通过调节微生物群落影响SOM转化路径. 原核菌群和真核菌群丰度受土壤含水率、pH值调控,AMX表层变形菌门占优,深层酸杆菌门主导,WQZ则呈现绿弯菌门随深度富集,且AMX担子菌门丰度显著高于WQZ.研究强调了木质素作为分子标记物在追踪SOM分布和周转中的应用,为高寒生态系统SOM循环及碳汇管理提供了理论依据.

以川西北高原红原县沼泽(WQZ)与亚高山草甸(AMX)土壤为对象,通过分析土壤剖面木质素分布、降解特征及环境因子互作机制,揭示SOM来源、转化过程及其对环境的影响.结果表明:AMX土壤pH值随深度升高,含水率较低,SOM和木质素含量随深度减少,且土壤质地呈现明显的垂向变化;WQZ土壤pH值层间差异小,含水率高((AMX的3倍),其SOM与木质素分布受季节性积水影响呈现先降后升趋势,其剖面均为黏壤土,细粒含量超过90%.两地SOM均源于被子草本维管植物. AMX表层高木质素含量与根系输入相关,并随深度显著减少;WQZ因长期淹水,木质素通过淋溶或生物扰动在深层积累,其相对有机质含量高于表层.AMX和WQZ土壤各层的愈创木基类单体酸醛比(Ad/Al)v与紫丁香基类单体酸醛比(Ad/Al)s值均大于0.6,表明木质素侧链经历了显著的氧化降解,并随土壤剖面加深而增强.与WQZ相比AMX土壤的去甲基/甲氧基降解作用更为强烈.土壤质地调控木质素稳定性,黏粉粒中木质素绝对含量(Σ8)较高,而砂粒与木质素相对同层土壤有机质的含量(Λ8)呈正相关,大粒径土壤物理屏障延缓木质素分解.环境因子通过调节微生物群落影响SOM转化路径. 原核菌群和真核菌群丰度受土壤含水率、pH值调控,AMX表层变形菌门占优,深层酸杆菌门主导,WQZ则呈现绿弯菌门随深度富集,且AMX担子菌门丰度显著高于WQZ.研究强调了木质素作为分子标记物在追踪SOM分布和周转中的应用,为高寒生态系统SOM循环及碳汇管理提供了理论依据.

The dynamic changes of soil organic matter (SOM) in alpine ecosystems were investigated using lignin as a molecular marker. Soils from a swamp meadow (WQZ) and a subalpine meadow (AMX) in Hongyuan County, on the northwestern Sichuan Plateau, were analyzed to examine the vertical distribution, degradation state, and environmental drivers of lignin within the soil profile. The results indicated that: In AMX, soil pH was observed to increase with depth, while water content remained low. Both SOM and lignin contents were found to decrease with depth, and soil texture exhibited clear vertical variation. In contrast, WQZ soils showed minimal inter-layer pH variation and high water content ((3times that of AMX). Affected by seasonal waterlogging, SOM and lignin in WQZ initially decreased and then increased with depth. All WQZ profiles were identified as clay loam, with fine particle content exceeding 90%. High lignin content in the AMX surface layer was attributed to root input and declined markedly with depth. In WQZ, long-term flooding was associated with lignin accumulation in deeper layers via leaching or bioturbation, resulting in higher relative lignin contribution to SOM at depth compared to surface layers. Ratios of guaiacyl (Ad/Al)v and syringyl (Ad/Al)s monomers in both soil types exceeded 0.6across all layers, indicating significant oxidative degradation of lignin side chains, which intensified with depth. Demethylation/methoxylation degradation was more pronounced in AMX than in WQZ. Lignin stability was regulated by soil texture: absolute lignin content (Σ8) was higher in clay silt, while sand content was positively correlated with the lignin contribution to SOM (Λ8) within the same layer. Prokaryotic and eukaryotic abundances were influenced by soil water content and pH. Proteobacteria dominated the surface layer of AMX, whereas Acidobacteria were more abundant in deeper layers. In WQZ, Chloroflexi were enriched with depth, and basidiomycete abundance was significantly higher in AMX than in WQZ.
