Abstract: Seven habitats in Anqing City were selected, leaf samples of Cinnamomum camphora and the corresponding soil samples were collected in either summer or winter, and then the variation characteristics of leaf N-P stoichiometry on seasons and habitats and their correlations, and the relationships with soils and leaf functional traits were analyzed. The result showed that, the average contents of leaf N were 10.91 and 11.10 mg/g, the mean values of leaf P were 1.04 and 1.07 mg/g, and the mean values of leaf N∶ P were 10.62 and 10.47, reflecting obvious N limitation. The variation coefficients ranged from 0.158 and 0.275, showing moderate and weak variation. The leaf stoichiometric characteristics varied in habitats and seasons in different habitats, but non-significant tendency was found. Leaf N and P represented isometric relationship in summer, while they presented allometric relationship that the allocation rate of leaf N is higher than leaf P. The allocation rate of leaf P in summer was higher than that in winter, according with the Growth Rate Hypothesis. Leaf stoichiometric characteristics of C. camphora were related with soil factors weakly, but correlated with leaf traits (e.g., leaf size and water content) closely.
