摘要：
Seasonal dynamics of CO2 efflux from gray forest soil have been studied using collars inserted to different depths in order to estimate the contributions and interaction of soil autotrophs and heterotrophs. The depth of collar insertion has proved to have an effect on CO2 efflux only in periods of the highest biological activity. It has also been shown for the first time that the level of competition between soil autotrophs and heterotrophs depends mainly on tree species rather than on soil type.
