AbstractTo understand the effects of leaf physiological and morphological characteristics on δ13C of alpine trees, we examinedleafδ13C value, LA, SD, LNC, LPC, LKC,Chla+b, LDMC, LMAandNarea in one-year-old needles ofPicea schrenkianavar.tianschanicaat ten points along an altitudinal gradient from 1420 m to 2300 m a.s.l. on the northern slopes of the Tianshan Mountains in northwest China. Our results indicated that all the leaf traits differed significantly among sampling sites along the altitudinal gradient (P<0.001). LA, SD, LPC, LKCincreased linearly with increasing elevation, whereas leaf δ13C, LNC, Chla+b,LDMC,LMAand Narea varied non-linearly with changes in altitude. Stepwise multiple regression analyses showed that four controlledphysiological and morphological characteristics influenced the variation of δ13C.Among these four controlled factors, LKC was the most profound physiological factor that affected δ13C values, LA was the secondarymorphologicalfactor, SD was the third morphologicalfactor, LNCwas the last physiologicalfactor. This suggested that leaf δ13C was directly controlled by physiological and morphological adjustments with changing environmental conditions due to the elevation.
