摘要
研究了５种不同林分土壤放线菌的分布特征及其与某些土壤因子的相关性。结果表明：①不同林分土壤链霉菌类群分布差异明显，以楠木林下分布的数量和类群最多。②链霉菌各种群在不同林分中有其一定的谱带，且各类群的组成和优势类群的组合有一定的差异。③土壤放线菌的分布与土壤肥力因素成正相关关系。
The distribution of actinomycetes in soils supporting 5 forest communities and its relationship with soil properties were analysed The results showed that:1 Significant differences in distribution of groups of streptomycetes existed between 5 communities The number and the groups of streptomycetes were most abundant in the soil under the forest community of Phoebe zhennan 2 Each group of streptomycetes in soil had its spectrum in different forest communities The groups′ composition and the dominant groups of streptomycetes varied with different forest communities 3 The distribution of actinomycetes was positively correlated with properties of soil fertility,and was affected by soil fertility
