摘　　要： 综述了大气CO2 浓度升高条件下 ,植物根际土壤环境、根际土壤微生物和植物菌根形成的变化趋势等方面的研究进展 .CO2 浓度升高 ,运转到根系的碳水化合物增加 ,根际环境、根际微生物活性、微生物群落结构以及菌根共生体的形成发生变化 .提出在CO2 浓度升高条件下 。 The changes of microbial communities in rhizosphere and the formation of mycorrhizae play an important role in affecting the dynamics of plant communities and terrestrial ecosystems.This paper summarized and discussed the effects of elevated atmospheric CO 2 on them.Under elevated atmospheric CO 2,the carbohydrates accumulated in root systems increased,and the rhizospheric environment and its microbial communities as well as the formation of mycorrhizae changed.It is suggested that the researches in the future should be focused on the effects of rhizosphere microbes and arbuscular mycorrhizae on regulating the carbon dynamics of plant communities and terrestrial ecosystems under elevated atmospheric CO 2.
