| 摘 要： | 应用Vodyanitsky提出的方法，根据元素组成数据，计算了施用猪粪对棕壤胡敏酸(HA)、富里酸(FA)热力学参数的影响。结果表明，HA、FA的形成都是自发进行的放热反应；与HA相比，FA的能态较低，分子结构有序度和热稳定性较高；FA在土壤中比HA更容易形成。施用猪粪后，HA、FA的能态降低，分子结构有序度和热稳定性也降低，形成的自发性减弱且放热量减少，这些与它们元素组成的变化有关。

| Abstract: | Vodyanitsky method was applied to calculate the effect of pig manure application on thermodynamic parameters of humic acid (HA) and fulvic acid (FA) in brown soil. The results showed that the formation of HA, FA was spontaneous and exothermic reaction. Compared to HA, the energy state of FA was low, but its order degree and thermal stability were high. The formation rate of FA was faster than that of HA. After the application of pig manure, the energy state, order degree and thermal stability of HA, FA all declined. And the changes of thermodynamic parameters were related to that of elemental compositions of HA and FA. |
