以北京地区板栗为材料，建立板栗年轮宽度、早材宽度和晚材宽度3项年轮结构指标的标准化年表和差值年表，分析板栗径向生长与气候因子间的相关关系和响应，并对可重建的气候因子进行筛选。结果表明：板栗年轮宽度和晚材宽度的年表质量明显好于早材宽度年表，其中差值年表优于标准化年表，其样本总体代表性达到93%，第1主成分方差解释量达到40%。差值年表与气候因子的相关分析和响应分析结果表明：年轮宽度、早材宽度和晚材宽度与各项气候因子间响应关系不同，在将来重建过去气候时，可利用年轮宽度和晚材宽度重建当年6月的温度，晚材宽度还可以重建当年7月的降水，早材宽度重建当年3月和4月的温度。%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.
