摘　　要：Biolog EcoTM微平板技术是研究微生物群水平多样性的一种重要方法。通过该方法对河南鸡公山自然保护区3种主要森林类型(落叶阔叶林、针阔混交林、杉木林)的土壤微生物群落多样性进行研究,结果显示:土壤微生物对单一碳源利用强度随着培养时间的增加呈递增的趋势,落叶阔叶林土壤微生物活性高于其他两种森林类型。3种森林类型土壤微生物对碳源利用差异性显著(p<0.01),森林植被类型直接影响土壤微生物功能多样性。分析表明,氨基酸是研究区域森林土壤微生物敏感碳源。Biolog EcoplateTM is an important approach of syudying community-level physiological profiles of microbes. Soil microbial diversity of three types of forests in Jigongshan Mountain Nature Reserve area of Henan Province,was studied by using Biolog EcoTM plates method. The result showed that utilization intensity of soil microbial on single carbon is in an increasing trend with the time of incubation and the metabolic capacity of soil microbial community under deciduous broadleaved forest is significantly higher than others. Utilization of different carbon resources is significantly different among forests（p 〈 0. 01 ）. The result indicated that the Amino acids were sensitive to the change of soil microbial communities.
