A STUDY ON THE RELIABILITY OF TREE RING DATA ——AN EXAMPLE OF HUASHAN PINE FROM SHAANXI
Wu Xiangding Shao Xuemei (Institute of Geography, CAS, Beijing 100101)
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.
