| 摘 要： | 以茂兰国家级自然保护区内三种植被（原生林、次生林、灌木林）下的土壤为研究对象,探讨了小生境土壤微生物数量、微生物量碳（BC）、微生物量氮（BN）、微生物熵（qSMBC）、基础呼吸及代谢熵（qCO2）的变化特征。结果表明：微生物数量、BC、BN、基础呼吸、qSMBC基本呈现石沟〉土面的趋势,qCO2则表现为土面〉石沟,即... |

| Abstract: | Characteristics of soil microbial amount,microbial biomass carbon(BC),microbial biomass nitrogen(BN),microbial quotient(qSMBC),basal respiration and metabolic quotient(qCO2) in different microhabitats were studied in three sites(virgin forest,secondary forest and shrubbery) of the Maolan National Nature Reserve.The results showed that the microbial amount,BC,BN,basal respiration and qSMBC were all higher in stone gully than those on soil surface,while the qCO2 was higher on soil surface than that in stone g... |
| Keywords: | microhabitat microbial biomass carbon and nitrogen microbial amount microbial quotient(qSMBC) metabolic quotient(qCO2) |
