酸沉降临界负荷计算模式的修正
A IMPROVED MODEL ON CALCULATED THE CRITICAL LOADS OF ACID DEPOSITION
-
摘要: 酸沉降临界负荷是酸沉降水平的函数,不同酸沉降水平下,矿物风化速率有数量级差别,因此,酸沉降临界负荷的计算应先使用判别方程计算平衡pH值,然后确定采用何种方法计算.在欧洲可以直接采用动态模式计算临界负荷,是因为其酸沉降水平能满足判别方程成立,但在中国大多数情况下不成立.Abstract: The critical load of acid deposition was a function of acid deposition level. The mineral weathering rate have different order of magnitude under different acid deposition level. It was necessary for identifying equation to be used for calculating balance pH values in soil solution, then the methods were selected to calculate critical loads. The critical load was able to be directly calculated by kinetic model in Europe, because acid deposition was satisfied identifying equation, but the situation was different in China.
