Abstract: This study on Pinus deszflora in Kangwon Province has been performed for the purpose of classifying its
growth area by geographical factors.
To classify its growth area, the basic data which had were the measured values for annual ring width from
cores were used. Individual variations in the measured values were removed through the standardization.
Regional mean chronologies were estimated from the standardized values. The growth area was classified by
the cluster analysis on the basis of the regional mean standardized indices. The results of this study shown that annual growth patterns to be clustered similar to geographical distribution in Kangwon Province. And the regional variations of annual growth patterns in the western part of Kangwon province were greater than those in the eastern part of Kangwon province.

 

Key words: annual ring width, standardization, standardized mlue, mean chnmologv, mean slandaniized indices.
