Microbial residue carbon (MRC) is an important source of soil organic (SOC) formation and plays a vital role in the accumulation retention SOC. Vegetation restoration effective strategy to restore degraded lands. However, there are no studies on how MRC profile changes with vegetation restoration. We evaluated (using amino sugars) its contribution SOC different depths (0-20, 20-50, 50-100 cm) during severely eroded forest (CK), restored (as ecological management), orchard development management model), secondary ideal control). biomarkers were extracted from profiles used measure microbial diversity community composition 16S rRNA). restoration, depth, their interaction each other significantly affected MRC, fungal (FRC), bacterial (BRC) contents. The content showed increasing trend for four models following order: CK < forest. Furthermore, increased depth rapid was substantially influenced by SOC, total nitrogen content, pH, diversity, phylum, phylum. In conclusion, model play roles red erosion area. These findings pivotal improving our mechanistic understanding regulation preservation ecosystem.
