| 摘 要： | 本文研究了福建三明小湖天然起源和人工起源的格氏栲林下土壤微生物的生态分布。两种起源的格氏栲林下土壤微生物中细菌占绝对优势,人工林芽孢杆菌所占细菌总数比例远大于天然林;天然林微生物总数、细菌、真菌以及固氮菌等生理类群的数量均高于人工林,而且,随着坡位的下降表现为由低至高的递增趋势。青霉和木霉是土壤真菌的优势种属,链霉菌属中的白色类群和黄色类群构成了土壤放线菌的主要组分,但在天然林中的数量明显低于人工林。

| Abstract: | The ecological distribution of soil microorganism under the natural and artificial original Castanopsis kawakamii stands was studied.The quantity of bacterium is greater than that of all other microorganisms under both stands, the proportion of Baciluss/bacterium under artificial stand ismuch greater than that under natural stand, the total microbe, bacterium,fungi and azotobacter under the natural stand are greater than those under artiftcial stand. Penicillium and Trichoderma are the dominant species over fungi, and Flavus and Albosporus are the main compositions of actinomyces, but the quantity of them under the artificial stand is greater than those under the natural stand. |
