Response Analysis of Tree-Ring Structure of Castanea mollisima to Climate Factors in Beijing
摘要
Abstract
The tree-ring structure,including tree-ring width,earlywood width and latewood width,of Chestnut trees (Castanea mollisima) in Beijing area was investigated to establish the standardized chronologies (STD) and residual chronologies ( RES) . The relationships between chestnut radial growth and climate factors,and the radial growth response to the climatic condition were analyzed to screen the climatic factors that could be used for climate reconstruction in Beijing area. Results showed that chronologies of ring width and latewood width had better quality than that of earlywood width. RES were superior to STD,and its overall sample representative reached 93% and the first principal component could explain 40% of variance. The correlation analysis and response analysis indicated that the responses of ring width,earlywood width and latewood width to climate factors were different. This study suggests that in the future climatic reconstruction,different tree-ring structure indicators should be used to reconstruct different climate factors. Specifically,the tree-ring width and latewood width could be utilized for the reconstruction of temperature in June,the latewood width could be utilized for the reconstruction of precipitation in July,and the earlywood width could be used for the reconstruction of temperature in March and April.关键词
