Recently, several studies have shown relationships between tree radial growth and
climatic factors. It is generally assumed in dendroclimatological studies that there exists
relationship between tree radial growth and the climatic factors. In this study, we
analyzed the relationship between tree radial growth and climatic factors that had been
collected from 4 sample sites in central urban area, Seoul in Korea. The standard growth
appeared better in the north and south aspects where the mean temperature was higher
than other aspects. The temperature variability of north and south aspects showed a
slightly higher than other slope. However, the precipitation showed opposite trend. This
study also indicated that spatial autocorrelation existed in standard growth. That is, there
exist spatial differences in tree growth due to micro climatic and topographical
variability. This result can be used to develop accurate regional process based model for
reasonable management of urban forest.


Key words: tree radial growth, climate change, spatial distribution
