The purpose of the article was to study the history of climate change in Linyi. According to the tree-ring samples of Ginkgo biloba collected from Xincun in Tancheng county,Linyi, tree ring widths had been detected based on the accurately determining time. After the assay was approved by the quality control procedure of COFECHA cross-determining time,ARSTAN annual tree-ring table developing process had been used to construct the standardization chronology, residual chronology,and autoregressive chronology. According to the research, the standardization chronology contained more information about the temperature compared to the other two chronologies. The standardization chronology about tree ring widths and the correlation analysis about meteorological data showed that tree ring width was positively correlated with mean temperatures of most months,while it was significantly negative with mean precipitations of most months. The correlation between tree ring widths and climatic factors were used to reconstruct the mean temperature of October from 1851 to 2012 in the Linyi,and the data about the mean temperature were classified as three stages: the first stage was the time during the period from 1851 to 1878 with a big fluctuation of temperatures; the second stage was the time from 1879 to 1950 with a small fluctuation of temperatures,and the temperature had a decrease trend overall; the third stage was the time since 1950, during which the temperature presented an upward trend overall, and this rising trend became more obvious. This reconstructed result not only extended the current record of meteorologic observation in the area of Linyi,but also provided basic statistics and reference frame to the research about climate change at the local during historical period.
