13、width chronology of Schrenk spruce at 10 mheight and the mean minimum temperature in Jun.Jul.,as well as the clear physiological significance of the trees,we reconstructed the mean minimum temperature series of Jun.Jul.for the past 174 a in the study area.We found that there were 35 cold years and 2
14、9 warm years in the past 174 a,with the longest partial cold period lasting for 28 a and the longest partial warm period lasting for 47 a.When combined with historical disaster information,the reconstructed series could better capture the known climate disasters in the past.A cycle analysis revealed
15、 that climate change in the study area may be influenced by multiple climate mechanisms.Moreover,the extreme years in this reconstructed sequence corresponded to the extreme years in other reconstructed sequences,which further demonstrated the feasibility of climate reconstruction using the chronolo
