CO_2浓度升高对土壤微生物及土壤酶影响的研究进展

Effects of Elevated CO_2 on Soil Microorganism and Enzyme∶a Review

概述了大气CO2浓度条件下,土壤微生物生物量C、土壤微生物区系、土壤细菌群落结构以及土壤酶的变化等方面的研究进展。并提出在CO2浓度升高条件下,根际微生物的优势种群的变化趋势和根系分泌物与根际微生物之间相互影响的研究是今后的研究趋向。

Microbial biomass C, microbial population, bacterial community and soil enzyme play an important role in affecting the microbial ecosystems. This paper summarized the effects of elevated atmospheric CO2 on the above microbial features. It is suggested that the future research shuld be focused on the dynamics of dominant microbes in rhizosphere and interaction between root exudates and rhizosphere microbes under elevated atmospheric CO2.
