Abstract

In order to assess the nature and the extent of acid deposition in the environment an ecosystem approach is often recommended. What do we then mean with ecosystem approach? - It can be defined as studies on an areal basis of basic ecosystem processes such as primary production, decomposition, mineralization and leaching and the integration of these processes as appearing in the biogeochemical cycling of elements. Preferably, there ought to be a coupling between trophic levels or processes representing different levels in order to describe and analyze the time behaviour of different functional parts of the ecosystem.
