Plant functional trait has been a hot topic of ecological research in recent years. The difference of functional traits among different populations will decide competitive advantages and cause the changes of community structure, further leading to succession. The typical forest communities under four different succession stages in Changbai Mountains were selected, and the relationship between the functional traits of stems and leaves of dominant species in different layers were analyzed, also, the relationship of functional traits and terrain factors were studied, besides, functional traits in different stages of successions were compared. The results showed that leaf area (SLA) was positively correlated with leaf nitrogen content (LNC) and stem phosphorus content(SPC), and negatively correlated with leaf dry matter content (LDMC); leaf thickness(LT) was negatively correlated with LDMC; LNC was positively correlated with leaf phosphorus content (LPC)、SNC、LDMC; SNC was positively correlated with SPC. Based on Grey correlation degree analysis, it indicated that the elevation was the most influential topographic factor on SLA, LNC, LPC, STD and SPC; LDMC and leaf thickness was most affected by slope aspect; and SNC was affected by slope position. There were differences in the functional traits of the plant species in tree layers of the forest communities, no obviously difference in shrub layers, as to the leaf functional traits, except of LDMC, LPC, SNC of the plant species in herbage layers had significant differences, other indicators no difference. LDMC and SLA are the main leaf functional traits that reflect the differences among communities succession.
