摘要:Results suggest ·· that nitrogen deposition leads to increased
tree growth. On plots with high inputs, growth of pine,
spruce and beech trees was consistently higher than expected
for given site conditions, stand age and density.
·· Higher growth increase occurred on sites with a low original
nitrogen status. These sites with limited nitrogen availability
are responding stronger to the atmospheric inputs,
as expected. Further research will test whether prolonged
high nitrogen deposition will have negative effects such as
declining growth or increased tree mortality.
··Temperatures above the long term mean during the growing
season also correlated with increased tree growth.
