摘　　要：对内蒙古大青山油松(Pinus tabulaeformis)、落叶松(Larix gmelini)人工林和白桦(Betula platyphylla)山杨(Populus davidiana)天然次生林3种林型根际、非根际微生物数量和根际效应进行了研究,结果表明3种林型的微生物数量为:细菌>放线菌>真菌;根际效应在0.27-5.32之间,相差近20倍。The work presented in this paper focuses on several aspects of the following： the rhizospheric microorganism＇s quantity of Pinus tabulaeformis,Larix gmelini and Betula platyphylla in Inner Mongolia Da Qingshan area,and these plants＇ rhizosphere effect.As a result of our experiments,we concluded that： the rhizospheric microorganism＇s quantity of these plants has something in common,the most abundant specie of microorganism is bacteria,the lest abundant specie of microorganism is epiphyte.The range of rhizosphere effect is from 0.27 to 5.32.
