中文摘要：
利用采自祁连山东部同一坡面油松树轮样芯,对不同年龄组油松树轮宽度年表指数与气候要素的相关分析,研究了不同年龄组油松径向生长对气候要素的响应.结果表明：不同年龄组油松树轮宽度指数对气候变化的响应不完全一致,即在该区域油松树木的径向生长对气候变化的响应与年龄有关.因此,使用该区域的油松树轮宽度指数年表重建过去气候变化时需要考虑年龄对树轮宽度与气候要素之间相关关系的影响,结果为进一步的树轮气候学研究的野外采样和室内分析等工作奠定了树轮生态学基础.
英文摘要：
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 a tree-ring 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.
