  "abstract": "目的探究林分类型对土壤团聚体周转特征的影响，从动态过程角度阐明森林植被驱动土壤结构发育与稳定的内在机制。方法以黄土高原典型阔叶林（山杨林）、针叶林（油松林）及其混交林为研究对象，采用稀土氧化物示踪结合室内培养试验，标记不同粒级团聚体，定量分析其形成、破碎量及周转速率与时间。结果3种林型土壤团聚体平均重量直径（MWD）差异显著（p<0.05），混交林MWD最高，稳定性最强，油松林MWD最小，稳定性最弱。培养期间，所有林型团聚体破碎量均大于形成量，呈净崩解特征。油松林周转最为剧烈，大团聚体平均破碎率为74%，且缺乏恢复韧性；混交林大团聚体保留率>50%，扰动后快速稳定；山杨林破碎与形成呈动态平衡。团聚体周转速率峰值出现在培养初期，大团聚体平均速率为油松林［0.026 g/（g·d）］>混交林［0.022 g/（g·d）］>山杨林［0.013 g/（g·d）］。培养中后期，混交林微团聚体周转时间延长，物理保护作用增强。方差分析表明，团聚体周转速率与破碎率受林型、粒级、时间三因素交互作用影响（p<0.05），而形成率主要受林型与粒级、林型与时间的双因素交互驱动（p<0.001）。结论混交林通过调控团聚体形成与破碎的相对强度，降低大团聚体周转速率，延长微团聚体周转时间，从而增强土壤结构的稳定性。",
