Age-Dependent Responses of Tree Radial Growth of Pinus tabulaeformis to Climate in Eastern Section of the Qilian Mountains
Pinus tabulaeformis Carr trees were sampled on the same slopes of the eastern section of the Qilian Mountains,and were divided in two age classes:young and old.Responses of the tree radial growth to climate change are investigated.It is revealed that there are some differences between the young and the old trees,and the radial growth responses of different tree age groups to climate change are not consistency.That is said that the response of radial growth of pine trees in this area to climate change has something to do with tree age.Therefore,using pine trees to create fl treering chronology for reconstructing a climate series must consider the age factor.This study settles groundwork of dendroecology to the benefit of dendroclimatology research,field sampling and laboratory analysis and SO on in the further.
