Abstract Under global climate change, changes in seasonal snow cover patterns significantly affect surface material cycling and microbial community composition. High-throughput sequencing and litter decomposition experiments were employed to study the relationships between soil microbial community characteristics and litter decomposition levels for different snow cover periods and thicknesses. The mass loss of litter was approximately 25–28%, the decomposition coefficient (k) was between 0.277 and 0.322, and k was significantly (p

季节性积雪下凋落物分解、微生物群落动态及其关系

摘要 在全球气候变化下，季节性积雪模式的变化显着影响地表物质循环和微生物群落组成。采用高通量测序和凋落物分解实验，研究了不同积雪时期和厚度下土壤微生物群落特征与凋落物分解水平之间的关系。凋落物的质量损失约为 25-28%，分解系数（k）在 0.277 和 0.322 之间，k 显着（p
