The duration of common chronology of the sites ‎is 131 years (1881-2011).Considering the strong correlation between ‎climatic data and growth rings width (P < 0.01), with positive coefficient, ‎we attempted to reconstruct the variables using combined linear and ‎quadratic regression analysis and ring growth width from 1881 to ‎‎2011.Accordingly, the highest maximum temperature was in 2001-2011 ‎decade and the lowest minimum temperature was during the decade 1981-‎‎1991.Over the recent three decades, the average and the annual maximum ‎mean temperature had an increase of 0.5°c and 1°c in comparison to the ‎previous century and the average annual minimum temperature has had a ‎decrease of 0.2°c.‎ SP - 153 EP - 166 AU - zarean, Hossein AU - Yazdanpanah, Hojjatollah AU - Movahedi, Saeid AU - Jalilvand, Hamid AU - Momeni, Mehdi AD - Department Of Climatology, Isfahan University , Isfahan,Iran KW - chronology KW - Dendroclimatology KW - growth samples KW - multiple KW - regression.
