研究了武功山高山草甸3个不同坡向土壤微生物生物量碳及其影响因素，结果表明：东坡土壤微生物生物量碳含量与土壤有机质含量显著高于南坡和北坡土壤，南坡土壤高于北坡；土壤速效钾(K)浓度以东坡土壤最高，南坡土壤次之，北坡土壤最低，但3个坡面土壤速效钾 K 含量之间的差异不显著；东坡土壤有效磷(P)的浓度极显著地高于南坡土壤和北坡土壤有效P浓度；不同坡面土壤铵态氮含量依次为北坡>南坡>东坡。土壤土壤微生物量生物量碳与土壤有机质含量和P浓度之间存在显著的正相关性，与速效钾K浓度之间相关性不显著，土壤微生物量生物量碳随着土壤铵态氮含量的升高而减小。

In the present paper, soil microbial biomass carbon (SMBC) in three hillsides of alpine meadow in Wugongshan mountains and its factors were studied. The results showed that both SMBC and soil organic matter (SOM) contents in the east slope were significantly higher than that in the south slope, and that in the south slope were as well higher than that in the north slope. Contents of available potassium (K) in the east slope were the highest, followed by that in the south slope, the lowest in the northern slope. Contents of available phosphorus (P) in the east slope were significantly higher than that both in south and north slopes. Soil ammonium nitrogen (NH4+-N) contents were the highest in the northern slope followed with that in southern slope and the lowest in eastern slope. SMBC contents in the three slopes were well correlated with SOM and available P contents. There were no significant correlation between contents of SMBC and K, but SMBC contents decreased with the increasing of soil ammonium nitrogen contents.
