keywords = {In Huoshan Mountain;sampling plots were set up at Qiliyu Farm for field investigation;trees;shrubs and grasses in 26 species were identified. The leaf area was measured with Li-3000A Leaf Area Meter;and the saturated photosynthetic rate (A#sub#area#/sub#) was determined with Li-6400 portable photosynthesis system. The leaf mass per area (LMA);The net photosynthesis based on mass (A#sub#mass#/sub#);leaf nitrogen content per unit area (N#sub#area#/sub#);leaf nitrogen content per unit mass (N#sub#mass#/sub#) and photosynthetic nitrogen use efficiency (PNUE) were quantified;the differences and interactions among three plant functional types (PFTs) were studied. The results showed that there were significant differences (p<0.05) in N#sub#mass#/sub#;A#sub#area#/sub#;A#sub#mass#/sub#;N#sub#area#/sub# and PNUE of three PFTs. The photosynthetic characteristics were significantly correlated with leaf nitrogen content;N#sub#mass#/sub# was significantly correlated with A#sub#area#/sub# (p<0.05);A#sub#mass#/sub# and PNUE;while N#sub#area#/sub# was significantly positively correlated with A#sub#area#/sub#;A#sub#mass#/sub# and PNUE (p<0.01).},
