| 英文摘要 | Plant-and microbially derived carbon (C) are the two major sources of soil organic matter (SOM), and their ratio impacts SOM composition, accumulation, stability, and turnover. The contributions of and the key factors defining the plant and microbial C in SOM along the soil profile are not well known. By leveraging nuclear magnetic resonance spectroscopy and biomarker analysis, we analyzed the plant and microbial C in three soil types using regional -scale sampling and combined these results with a meta-analysis. Topsoil (0- 40 cm) was rich in carbohydrates and lignin (38%- 50%), whereas subsoil (40- 100 cm) contained more proteins and lipids (26%- 60%). The proportion of plant C increases, while microbial C decreases with SOM content. The decrease rate of the ratio of the microbially derived C to plant-derived C (C-M:P) with SOM content was 23%- 30% faster in the topsoil than in the subsoil in the regional study and meta-analysis. The topsoil had high potential to stabilize plant-derived C through intensive microbial transformations and microbial necromass formation. Plant C input and mean annual soil temperature were the main factors defining C-M:P in topsoil, whereas the fungi - to-bacteria ratio and clay content were the main factors influencing subsoil C-M:P. Combining a regional study and meta-analysis, we highlighted the contribution of plant litter to microbial necromass to organic matter up to 1-m soil depth and elucidated the main factors regulating their long -term preservation. |
