摘要：Sulphur deposition has decreased
on about one third of 230 evaluated
monitoring plots since 1998. This reduction
shows the positive effects of
pollution abatement strategies.
Atmospheric nitrogen inputs have remained
unchanged on around 90 %
of the plots. The reduction of nitro-
·
·
gen deposition remains an important
task for environmental policy.
The data provide the basis for determination
of air pollution effects
on forest ecosystems and for the development
and application of critical
load calculations (see following
chapters).
