Data for study of divergent microbial strategies under topographically decoupled disturbances linking contrasting soil carbon fates following tree mortality

This deposit provides the curated soil, microbial and genomic trait datasets used to reproduce the analyses in the study on topographically decoupled tree mortality disturbances, microbial strategies and soil organic carbon (SOC) dynamics in a subtropical forest. Files include soil physicochemical properties, bacterial and fungal amplicon feature tables (16S, ITS), metagenomic gene count tables and functional annotations for carbon-degrading and terminal-electron-acceptor utilization genes, genome-derived gene copy number variation matrices for bacterial and fungal taxa, and derived community and model outputs (e.g. microbial composition summaries and XGBoost cross-validation results). These tables correspond to the input data required by the R scripts in the companion code repository (https://github.com/zhangdx2025/tree-mortality-soil-carbon) and allow regeneration of the numerical results and figures in the associated manuscript. Raw sequencing reads are not included here; their access information is provided in the article.本数据存档提供经人工精选整理的土壤、微生物组及组学性状数据集，用于复现该项针对亚热带森林中地形解耦型树木死亡干扰、微生物生存策略与土壤有机碳（Soil Organic Carbon，SOC）动态变化的研究的分析结果。数据集包含土壤理化性质数据、细菌与真菌扩增子特征表（16S、ITS）、宏基因组基因计数表，以及碳降解基因与末端电子受体利用基因的功能注释结果；同时涵盖细菌和真菌类群的基因组衍生基因拷贝数变异矩阵，以及衍生的群落分析结果与模型输出（例如微生物组成总结和XGBoost交叉验证结果）。上述表格与配套代码仓库（https://github.com/zhangdx2025/tree-mortality-soil-carbon）中的R脚本所需的输入数据完全匹配，可用于复现相关论文中的数值结果与图表。本次存档未包含原始测序读数，其获取信息已在文章中予以说明。
