The plant residue with more lignin has a higher humificationcoefficient. As the residue containing more N is more favorable to the formation of soil microaggregate.
其中含木素较多的植物残体，表现为腐殖化系数较高，含氮多的植物残体，则有利于土壤微团聚体的形成。

Humificationcoefficient did not changed proportionately with temperature and rainfall and was multiply influenced by environmental factors, especially soil properties.
