Tree-ring samples of Pinus thunbergii Parl at eastern Tashan in Shandong Province were collected to integrate the tree-ring stable carbon isotope series. In order to remove the influence of atmospheric CO_2, extract the high frequency part of the tree ring delta~(13)C. Analysis the response of tree ring delta~(13)C series and climate factors, found that the response between tree ring delta~(13)C and temperature is obvious than precipitation. There exists a lagging effect of the influence of both temperature and precipitation on tree-ring delta~(13)C in some extent. This results indicated that tree ring delta~(13)C in Tashan can record the winter climate change. On the basis of correlation analysis, utilize the regression equation to reconstruct near seventy years' average temperature in winter and spring season (i.e., from December last year to May current year). Analysis found that the rebuilding temperature series shows an obviously rise trend which cold and warm temperature change alternately.
