A highly positive correlation existed between the mineralization rate at effective accumulated temperature of 105 ℃ ( Y '_ ( 105 )) and mineralization power , and Y '_ ( 105 ) was closely negatively related to the availability of mineralized N.
矿化速率是土壤氮矿化过程的特征值，有效积温105℃时的矿化速率（Y（105）~′）与土壤氮矿化能力及矿化氮有效性均密切相关。
