摘　　要：土壤微生物和土壤酶活性是反映土壤肥力最为重要的生物学指标之一。文章综合论述了不同林分土壤微生物种群和数量的分布及其影响因素,并对土壤酶活性对土壤肥力的影响做了分析,显示土壤微生物、酶活性与土壤养分有显著的相关关系。Soil microorganism and soil enzyme activity is one of the most important indexes influencing the soil fertility. This article discussed the strain, amount, distribution of soil microorganism and influence factors in the forest stand, and analyzed the effect of soil enzyme activity. The results show soil microorganism, enzyme activity and soil nutrient has significant correlation, and can be used as a valuable index.
