Pinus tabuliformis on ridge as one of the typical plant communities plays an important role in biodiversity maintenance and ecological service function achievement. The objective of this study was to understand how leaf functional traits responded to altitudinal gradients. Ten P. tabuliformis on ridge traits were researched with typical sampling method in this study. The results showed that: (1) leaf length(LL), leaf nitrogen content(LNC), leaf phosphorus content(LPC) of 1-3yearold leaf and chlorophyll concentration of 1yearold leaf of P. tabuliformis on ridge were below nonridge. However, the leaf dry matter content(LDMC) and stomata density(SD) of 1yearold leaf of P. tabuliformis on ridge were higher than nonridge. (2) The leaf funcation traits of P. tabuliformis on ridge, including leaf thickness(LT), specific leaf area (SLA) of 1-3yearold leaf, LPC of 1yearold leaf increased linearly with increasing elevation, but LL, LDMC, leaf carbon concentration (LCC), Chl(a+b) of 1-3yearold leaf, SD of 1yearold leaf decreased significantly with increasing elevation. (3) LNC was positively correlated with LPC of 1-3yearold leaf; LDMC negatively correlated with LPC of 1-2yearold leaf; LL was positively correlated with LNC, LPC of 2-3yearold leaf; LKC was positively correlated with LNC, LPC of 2-3yearold leaf. The unique habitat condition of the ridge has created the unique growth strategy of P. tabuliformis. P. tabuliformis on the ridge showed diversified adaptive strategies to adapting varing environmental factors associated with changes in altitude.
