The formation of soil aggregates was remarkable for the farmland under conservation tillage, compared to that under rotary tillage. For conservation tillage, the organic matter(OM) content in soil aggregated was found more in larger aggregated than in smaller ones. Our study showed that the change of functional groups in soil organic matter can be monitored easily by using a reflection type FTIR analyzer. A ratio of aromatic to aliphatic(Ar/Al) functional group determined by FTIR sensitively reflected the change of decomposition of OM more than a ratio of aromatic to amide(Ar/Am) functional group. The soil under conservation tillage had a greater value of Ar/Al than rotary tillage. The greatest Ar/Al value in the surface soil was found under conservation tillage, followed conventional cultivation and rotary tillage(control). Further study is needed to investigate the mechanistic relationship between soil OM functional groups and soil carbon sequestration.

保护性耕作土壤团聚体的形成显著高于旋耕耕作。保护性耕作条件下，大团聚体土壤有机质含量高于小团聚体。研究表明，用反射式FTIR分析仪可以方便地监测土壤有机质中官能团的变化。FTIR测定的芳香族/脂肪族(Ar/Al)官能团比芳香族/酰胺(Ar/Am)官能团更能灵敏地反映OM分解的变化。保护性耕作土壤的Ar/Al值高于旋耕土壤。表层土壤Ar/Al值以保护性耕作最大，其次为常规耕作和旋耕(对照)。土壤有机质官能团与土壤固碳之间的机理关系有待进一步研究。
