| 摘 要： | 为探究福建省南平市洪涝灾害受损区不同林型自然恢复过程的土壤微生物群落变化特征,以该区毛竹林、杉木林和次生阔叶林等3种主要林型为研究对象,采用Biolog-ECO板技术研究林地受损、受损自然恢复7年(自然恢复)和未受损3个阶段的土壤微生物群落碳源代谢多样性.结果表明:对不同林型而言,杉木林和次生阔叶林自然恢复样地对6类碳源利用情况优于受损样地,微生物整体活性优于未受损样地,而毛竹林仅对3类碳源利用较好,微生物整体活性低于未受损样地.杉木林和次生阔叶林自然恢复样地微生物多样性指数H、E和D显著优于受损样地(P < 0.05),而毛竹林2个样地差异不显著.林型与恢复阶段的交互作用显著影响了除多聚物外的其他碳源与H、E、D.对3种林型恢复类型土壤微生物群落具有分异作用的主要碳源是氨基酸类、碳水化合物类和羧酸类.综上所述,3种林型自然恢复过程中土壤微生物总体活性上升,但次生阔叶林和杉木林微生物群落恢复程度好于毛竹林.
