稳定化垃圾填埋场中腐殖土的特性及资源潜力分析综述
腐殖土作为垃圾填埋场稳定化处理的产物，具有优良的团聚结构、保水能力和养分保留特性。本文系统综述了腐殖土的物理、化学与微生物特性：其粒径分布不均、干密度较高，但有机质和养分含量高于天然土壤；化学性质呈中性至弱碱性，盐分与重金属（如Cu、Pb、Cr等）含量需关注环境风险；微生物群落以Proteobacteria、Actinobacteria等为主，参与有机质转化与温室气体减排。腐殖土在生态修复（矿山复垦、退化土地治理）、非食用农业及园艺生产中展现出巨大资源化潜力。通过整合生物炭、蛋白基产品及堆肥技术可进一步提升其安全性与效能。未来需构建多指标评估体系，深化腐殖化机理研究，完善标准化管理，以支撑“无废城市”与“双碳”目标实现。
