Abstract: The soil microbial distribution of bacteria,fungi,and actinomycetes in five different Larix gmelinii forests[(A) Ledum palustre-Larix gmelinii virgin forest,(B) herbage-Larix gmelinii virgin forest,(C) Betula fruticosa-Larix gmelinii virgin forest,(D) Larix gmelinii forest burned-over areas,and (E) clearcut Larix gmelinii forest] in 0 - 10,10 - 20,20 - 30 cm soil layers was studied in the National Forestry Ecosystems Station of Inner Mongolias Great Xingan Mountains using the dilution-plate method. Results showed that in the different forest types,soil microbes varied in quantity,category,and vertical distribution(P<0.05). Also,bacteria were dominant accounting for 80.2% - 96.8% of the microorganisms. Numbers of all microorganisms in the Larix gmelinii forests were in the order:A>B>C>D>E;whereas bacteria were A>B>C>D>E,fungi were E>C>A>B>D,and actinomycetes were A>B>D>E> C. In virgin forests actinomycetes in the 10 - 20 cm layer were greater than the 0 - 10 cm layer;but vertical distribution of bacteria and fungi decreased(P<0.05) with the increasing vertical depth.[Ch,4 fig. 1 tab. 15 ref.]
