  "abstract": "目的崩岗侵蚀是南方花岗岩红壤区最严重的土壤侵蚀类型，揭示其治理先锋树种马尾松林土壤结构稳定性及抗蚀能力的区域分异规律与驱动机制，对区域生态恢复与可持续经营具有重要意义。方法选取我国南方5省8个典型崩岗侵蚀区马尾松林地［湖北崇阳（CY）、江西新余（XY）、江西赣县（GX）、江西鹰潭（YT）、广东五华（WH）、福建福州（FZ）、广东湛江（ZJ）、广西梧州（WZ）］，通过湿筛法测定土壤团聚体稳定性指标（MWD、GMD、R0.25），计算土壤可蚀性K值，结合冗余分析（RDA）和系统聚类分析，探讨土壤团聚体稳定性及可蚀性的区域分异特征及其关键驱动因子。结果1）8个样地土壤团聚体稳定性呈现显著的区域分异特征，XY表现出极高的团聚体稳定性［MWD 1.78 mm，R0.25为93.54%，K值为0.074（t·hm²·h）/（hm²·MJ·mm）］，而WZ、WH等样地处于低稳定性水平［MWD<1.00 mm，K值>0.220（t·hm²·h）/（hm²·MJ·mm）］，整体呈“江西地区优于华南地区”的空间分布格局；2）系统聚类分析将8个样地划分为3个类型区：Ⅰ类（高稳定性-低可蚀区，仅XY）、Ⅱ类（中等稳定性-中等可蚀区，包括CY、FZ、GX、ZJ）和Ⅲ类（低稳定性-高可蚀区，包括YT、WH、WZ）；3）WZ样地呈现高有机碳（57.31 g/kg）、低团聚体稳定性（MWD 0.81 mm）、高可蚀性［K值为0.223（t·hm²·h）/（hm²·MJ·mm）］的异常模式，即高碳低稳现象，表明在pH<4.50的条件下高有机碳积累未能有效提升团聚体结构的稳定性。结论崩岗侵蚀区马尾松林土壤抗蚀能力受有机-无机复合胶结机制协同调控，区域土壤结构改良应以提升有机碳品质、调节pH至近中性范围、促进活性铁铝氧化物形成为核心，XY模式（高碳、高氮、近中性pH）可作为区域参照目标。",
