摘　　要：以武功山干扰较为严重的金顶区域(海拔1900m)为研究对象,对不同干扰程度的土壤活性有机碳进行研究,分析武功山山地草甸退化演变机制。结果表明,随着干扰程度的加剧,土壤微生物量碳、土壤可溶性碳、土壤易氧化碳减少量随之增加。土壤微生物量碳、土壤可溶性碳、土壤易氧化碳分别与不同干扰程度呈负相关关系。因此,人为干扰已造成武功山金顶区域土壤活性有机碳减少,金顶区域草甸已发生不同程度退化。Taking the serious interference Jinding area of Wugong Mountain as the research object ,studying the soil organic carbon in different levels of disturbance, analyzing the evolvement mechanism of the meadow degradation. The results show that with the increasing degree of interference,the decrease amount of soil microbial biomass carbon, the soil soluble carbon and the easy oxidation is increasing. Under different disturbance degree,the soi l organic carbon and soil microbial biomass carbon, the soil soluble carbon and the easy oxidation of carbon was significantly posit ively related to relat ionship, and the meadow patches with more disturbance has appeared different degrees of degradation.
