Résumé :
|
This paper reviews how biota, especially vegetation, may influence the physical and chemical pathways of acquisition of solutes by drainage water. The major processes involved are : 1-effects of canopies on atmospheric deposition ; 2-effects of transpiration ; 3-effects through soil formation and mineral weathering and 4-effects through transformation and uptake of nutrients. After giving specific examples of each of these groups of processes, a number of specific ecosystems will be discussed in terms of their overall H+ budget.
