Taking Elaeagnus mollis Diels and seven dominant woody species in its community from Yicheng County of Shanxi Province as research objects， leaf traits including specific leaf area （SLA）， nitrogen content in leaf per unit area （Narea）， leaf dry matter content （LDMC） and photosynthetic nitrogen use efficiency （PNUE） were compared， and correlations of SLA value with LDMC and PNUE values were analyzed. The results show that there are different degree variations in four indexes of leaf traits of E. mollis， Vitex negundo var. heterophylla （Franch.） Rehd.， Broussonetia papyrifera （Linn.） L’Hér. ex Vent.， Lespedeza bicolor Turcz.， Caragana microphylla Lam.， Rosa xanthina Lindl.， Amygdalus davidiana （Carrière） de Vos ex Henry and Periploca sepium Bunge， in which， SLA value with the largest coefficient of variation （40.4％）， and LDMC value with the lowest coefficient of variation （10.3％）. Compared with other tested species， SLA and PNUE values of E. mollis are the lowest （103 cm^-2·g^-1 and 108 μmol·mol^-1·s^-1, respectively）， while its Narea value is the highest （0.243 g·m^-2）， and its LDMC value is also relatively high （0.380 g·g^-1）. SLA value of eight tested species show an extremely significant positive correlation （P＜0.01） with PNUE value， and a significant negative correlation （P＜0.05） with LDMC value， correlation coefficient are 0.923 and -0.718, respectively, indicating that SLA value is an important parameter of leaf photosynthetic capacity and resource utilization ability. It is suggested that compared with other dominant woody species， E. mollis is more sensitive to environmental change， and has a poor environmental adaptability.
