[Responses of Chinese pine tree ring in Shenyang suburb (Fu Mausoleum) to global temperature fluctuation].

In this paper, the correlations between the variations of Chinese pine (Pinus tabulaeformis Carr.) tree ring width in Shenyang suburb (Fu Mausoleum) and the local temperature variables, Global Surface Air Temperature Anomaly (GSATA) from 1880 to 2004, Global Land-Ocean Temperature (GLOTI) from 1880 to 2004 and North Hemisphere Temperature Anomaly (NHTA) from 1880 to 2004 were studied. Some close correlations were detected, and the local temperature variables, GSATA, GLOTI and NHTA had some similar influences on the Chinese pine tree ring width. The air temperature in last winter (December and January) and in spring (April and May) affected the growth of Chinese pine significantly (P < 0.05). There existed a 3-8-year periodicity of the variation of Chinese pine tree ring width and the GSATA, GLOTI and NHTA, and the 19.3-year and 23.2-year quasi-periodicity of the variation of Chinese pine tree ring width corresponded with the 20.8-year quasi-periodicity of GSATA, GLOTI and NHTA. This study suggested that the Chinese pine tree ring width in Shenyang Fu Mausoleum had positive correlations with global-scale temperature fluctuation, and the temperature increase in the past had a positive effect on the Chinese pine growth.
