树木年轮蓝光强度研究进展

Research Progress on Blue Intensity of Tree Rings

蓝光强度是一种新的反映树轮密度的指标,自2002年提出以来,由于其操作简便且可能提供木质素密度的信息,在重建北半球高纬度、高海拔地区夏季气温变化方面展现出巨大潜力。对蓝光强度的原理和试验方法进行了概述,并对国外蓝光强度研究所取得的进展进行总结。通过对其存在的几个亟待解决的问题及现有的解决方案的论述,进一步明确蓝光强度的研究潜力,尤其是针对在国内开展蓝光强度研究的可能性进行了探讨。

Blue intensity is a new indicator of tree-ring density.Since its introduction in 2002,it has shown great potential for reconstructing summer temperature changes at high latitudes and high altitudes in the northern hemisphere due to its ease of operation and possible information on lignin density.This paper summarizes the principles and test methods of blue intensity,and summarizes the progress made by foreign blue intensity research.Through the discussion of several problems that need to be solved and the existing solutions,the research potential of blue intensity is further clarified,especially the possibility of conducting blue intensity research in China.
