Humification coefficient did not changed proportionately with temperature and rainfall and was multiply influenced by environmental factors, especially soil properties.
The content of methyl functional group of humus is an important index to evaluate the humification of soil.
胡敏酸甲氧基功能团的含量多寡是衡量土壤腐殖质化的重要指标。

The plant residue with more lignin has a higher humification coefficient. As the residue containing more N is more favorable to the formation of soil microaggregate.
