本文介绍了生态系统对酸沉降的临界负荷的概念及一般确定过程。叙述了用MAGIC区域数学模型求算临界负荷的方法 ,包括计算单元的选择、采样点的布设及样品的采集、土壤参数的确定、地表径流和地表水参数的确定以及临界负荷的计算方法
This paper presents the concept and general determination of the critical load on acid deposition by ecosystems. The method of calculating the critical load with the mathematical model of MAGIC area is described, including the selection of calculation unit, the arrangement of sampling points and samples, the determination of soil parameters, the determination of surface runoff and surface water parameters and the calculation method of critical load
