| 摘 要： | 依据陕西华山的华山松树木年轮宽度、最大密度与最小密度年表，以及对树木生长模拟结果，本文分析了树木径向生长对气候因子（气温和降水）的响应状况。结果表明树木年轮生长的多种指标均能相互印证，并具有生理学意义，从而证实了它们作为气候变化的代用资料是可靠的。这不仅强调了树木年轮多途径分析的必要性，而且为重建过去气候变化提供了依据。

| Abstract: | Using tree ring chronologies of width, maximum and minimum desity for Huashan Pine from Huashan, Shaanxi, and the tree growth model, the response of tree radial growth to climate factors (e.g., air temperature and precipitation) was studied. The results show that various growth indices can be confirmed by each other, which indicates that tree ring indices are reliable proxy data for climate change sutdy. This emphasizes that it is necessary to use various tree ring data to perform study and provides a solid basis for climate reconstruction. |
