Abstract:

In this paper data of tree-ring width were used to establish the chronologies of tree-ring width of the survival Korean pine (Pinus koraiensis) after fired, i.e. Standardized chronology (STD), Residual chronology (RES) and ARSTAN chronology (ARS). The chronology features were further analyzed. The results showed that: 1) the fluctuation of tree radial growth displayed a certain periodic and the average ring width was 1.615 mm with the lowest value happened in 1889—1917 and the highest one in 1958—1995;. 2) The fired samples had a good consistency, containing a lot of high frequency information and some low frequency information, which were closely related to the atmospheric environment with an apparent "lag effect" to climate change; 3) The RWI values changed in the cycles of 5.2 years and 3.6-3.9 years.
