Detailed Description

氮预算模型

(1)Stinner(1981)修正的方程计算氮从活植物体到枯枝落叶的转移:

           

式中,NF是氮从植物体到枯枝落叶去区室的净流量;UF植物对氮的吸收;FX是大豆固定的氮;HG是收割作物中的氮;TF是氮从植物到树冠溶液的流动;CS是迁移到昆虫消费者中的氮。

(2) 氮从土壤有机质到矿物池的迁移体现了净矿化作用,并且可以用下面Stinner1981)修正的关系式计算:

          

式中,MIN是氮的净矿化作用;CR农作物对氮的吸收率;WE杂草对氮的吸收率;LO是过滤输出的氮;DN是反硝化作用输出的氮;IM是被固定的氮;FZ是肥料输入的氮;PR是降水量;LT是枯枝落叶输入的氮。
