【摘要】 采用秦岭四个地点的树木年轮样本，进行了密度量测，建立各自的最大密度与最小密度年表。分析结果表明，密度变异对气候变化有显著的响应，这些年表可以成为表征过去局地气候的代用资料．更多还原

【Abstract】 By using densitometry analysis,the maximum and minimum tree-ring densitychronologies have been developed from four sites in the Qinling Mountains of China. Itis shown that the density variation responds to the climatic change significantly. Thedensity chronologies can be used as substitute data which indicate past local climate inthe mountains.更多还原
