快速优先流和空间变异性被认为是养分和污染物渗入地下水的重要参数,特别是对于吸附溶质。虽然这被广泛接受,但在试验中没有得到很好的考虑,因为许多实地方法不能解释这两种现象。我们讨论了现有的方法测量溶质运移和浸出的适用性。监测箱方法并不广为人知,但可能是一个令人感兴趣的选择。给出了验证实验和应用实例。
Fast preferential flow and spatial variability are known to be important parameters for nutrient and pollutant leaching into the groundwater, especially for sorbing solutes. Although this is widely accepted, they are not well considered in trials, because many field methods cannot account for either of the phenomena. We discuss the suitability of existing methods of measuring solute transport and leaching. The Monitoring Box method, which is not widely known, may prove to be an interesting option. Validation experiments and examples for its application are given.
