摘要：

In order to study the possible interactions between air pollution and climate conditions in Mediterranean evergreen broadleaf species, since 1987 we have been monitoring the annual and infra-annual variations in crown density of Quercus ilex L, (holm oak) in a permanent sample plot. The behaviour of crown density has bear compared with litterfall pattern and aging processes in leaves. The results of this study confirm the important impact of climate on crown condition in Mediterranean broadleaves, so that even the role of non-acute pollution can be disguised. Xeromorph adaptations in helm oak leaves are also a mechanism providing a greater protection against pollutants.
