摘要 自由大气CO2浓度升高(简称FACE,即Free A ir CO2Enrichment)对陆地生态系统的影响是全球变化研究中的一个热点。综述了FACE条件下,农田土壤植物生物量质量变化和土壤微生物对植物的反馈作用,以及土壤痕量气体排放的趋势变化。 The importance of soil ecology is attributed to " the missing carbon sink" global cycle in the world change. The growing concentration of atmospheric CO2 ( free air CO2 enrichment) is focused on nowadays. This paper summarizes the results about soil organic microbe (SOM) reaction, and the relationship of SOld between plant residue and effects of soil trace gases emission in the free air CO2 enrichment.
