摘要
在内蒙古不同的草原生境条件下 ,采用氯仿熏蒸浸提法对土壤微生物生物量—碳 (MB- C)进行了测定分析。MB- C与土壤有机质含量呈正比 ;过度放牧会导致土壤中 MB- C的明显减少 ,而围栏保护和适度放牧有助于该指标的恢复 ;蘑菇圈土壤的 MB- C与其发育过程有密切关系。
The microbial Biomass C(MB-C)in soil of different habitats of steppe were determined by an extraction method.The MB-C has postitive correlation with the amount of organic matter in the soil.Excessive grazing leads to decrease of the MBC,fencing without grazing and moderate grazing contribute to restoring of the MB-C.The MB-C in soil of the fairy ring has associated with the process of the ring's developing.
