研究长期耕作管理下土壤有机碳（SOC）固持能力及其积累机制是当前农业可持续发展基础研究的前沿。我国南方山区稻作梯田是国际社会公认的全球重要农业遗产，本研究旨在剖析其千年可持续水稻生产下有机碳的积累特征，探索基于自然的农田固碳技术途径。以我国南方山区5处典型稻作梯田系统为研究对象，采集0~20 cm（表土）、20~40 cm（心土）和40~60 cm（底土）深度土壤样品，分析土壤有机碳形态与分布特征，同时采用生物标志物分子提取和GC-MS鉴定技术，分析木质素及氨基糖含量变化来解析有机碳的不同来源。结果表明：供试5处梯田表土有机碳积累水平差异极大，发育于沉积岩的四川新山梯田和高坎梯田黏粒含量高达40%，各层有机碳含量在15.58~47.78 g·kg-1范围内，而发育于花岗岩的江西上堡梯田、浙江...
