The relationship of Pinus mussoniana radial growth with climate change in the upstream of Three-gorges Reservoir Area in China was assessed by dendrochronological techniques including correlation functions and single-years analysis.The results showed that Pinus mussoniana growth in the high and low elevations had a significantly different response to temperature and precipitation.In the low elevation,Pinus mussoniana growth was significant correlated with the mean precipitation and the humid indexes of of May and June.But in the high evelvation,it had a more complicated relationship with its environment.Besides the mean temperature of May and June,the humid index of last Novemeber was significantly correlated with the Pinus mussoniana tree-ring width.Therefore,the relationship of the same tree species with different environmental gradients was different.
