摘 要 ：研究了培养 4 5 d的小叶章根际土壤微生物和二氧化碳 ,甲烷及氧化亚氮产生与消耗之间的关系。结果表明好氧微生物与厌氧微生物的空间分布与甲烷 ,二氧化碳及氧化亚氮的产生和氧化有着密切的关系。好氧微生物与甲烷产生呈负相关 ,与二氧化碳和氧化亚氮的产生呈正相关关系。厌氧微生物与甲烷的产生呈正相关 ,与二氧化碳和氧化亚氮的产生呈负相关关系。

Abstract:To understand the relationship between microbes and greenhouse gases, four soil cores dominated by Calamagrostis angustifolia were investigated to determine bacterial community as well as the production and consumption of methane (CH_4), carbon dioxide (CO_2) and nitrous oxide (N_2O) after 45 days incubation in an open area. Aerobic and anaerobic microorganisms were counted to evaluate the bacterial community, and the results suggested a significantly negative correlation between the aerobic and anaerobic. ...
