We investigated the relationships between climatic factors and annual tree-ring data such as stable carbon isotopic composition and tree-ring width of a Japanese pine tree (Pinus thunbergii) with annual rings from 1955 to 2002, which was collected at the site of Environmental Studies Hall in Nagoya University. The climatic factors used are: month total values of sunshine duration and precipitation, month average values of day average temperature, relative humidity and vapor pressure in the Nagoya area. The annual rings of the sample are very wide in the periods from 1960-1970. This remarkable growth might be related with the local environment changes not with the regional environment changes because the annual-ring width shows no correlation with the climatic factors. The δ^<13>C fluctuations of the annual rings in the period from 1955 to 1979 are different from those in the period from 1980 to 2002. The result shows the change factors of δ^<13>C values in the two periods are different. In the period from 1955 to 1979, no-climatic environmental factors, that is, artificial factors such as air pollution effect the δ^<13>C fluctuations because they are not related with the climatic factors. In the period from 1980 to 2002, on the other hand, the month average values of relative humidity are good correlative with the δ^<13>C fluctuations of earlywood and latewood fractions, relatively.
