Abstract:

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.

Key words: Dendrochronology, Tree-ring ecology, blue intensity, temperature reconstruction, tree-ring density
