【摘要】Changes of microbial biomass and functional diversity in red soil were determined under different land use types. Results showed that land use type significantly influenced the various aspects of soil quality. Soil microbial biomass was higher in paddy soil, but medium in grassland and forestry, while in arid-land soil the contents of microbial biomass C and N were minimum (4.3% and 13.7% of those in paddy soil respectively). Microbial functional diversity was higher in paddy soil, while bacterial diversity was lower in arid-land, forestry and grassland, fungal functional diversity was lowest in arid-land soil. Microbial biomass and functional diversity, as an early and sensitive indicator, could be used to evaluate the effect of land use type or management on soil quality.%研究了不同农林利用方式下红壤微生物生物量和代谢功能多样性等土壤质量指标的变化.结果表明:不同利用方式对土壤质量各指标造成了显著的影响;稻田的微生物生物量碳、氮最高,林地和草地微生物生物量次之,旱地的微生物生物量碳、氮最低(分别是稻田利用方式的4.3% 和 13.7%);稻田的微生物代谢功能多样性最高,旱地、林地和草地的细菌代谢功能多样性较低,旱地的真菌代谢功能多样性最低;微生物生物量和代谢功能多样性可以作为反映土壤质
