In order to understand the nutrient cycling of evergreen broad-leaved forest ecosystem in Fujian Province, the typical forests of Wuyishan, Tianbaoyan and Huboliao National Nature Reserve were studied. The carbon (C), nitrogen (N), phosphorus (P) concentrations of plant, litter and the topsoil (0-10cm) were explored. We had mastered the correlation among them through analyzing the ecological stoichiometry and the redundancy analysis (RDA) was used to study relationships between the measurement results and environmental factors. The results show that (1) the C, N and P concentrations in vegetation and litter layers of Huboliao (except the N concentration of tree layer) were higher than those of Wuyishan and Tianbaoyan. The C and N concentrations in topsoil of Wuyishan were higher than those of Tianbaoyan and Huboliao, while the trend of P concentration was Tianbaoyan > Wuyishan > Huboliao. (2) P was the main limiting factor of plant growth in evergreen broad-leaved forests. The lack of P concentration in topsoil was seriously harmful for nutrient cycling of evergreen broad-leaved forest ecosystem. (3) The concentrations and stoichiometry characteristics of C, N and P in leaves had significantly positive correlations with those in the litter, and had significantly negative correlations with those in the topsoil. The nutrient turnover rate of evergreen broad-leaved forest ecosystem was slowly due to the slower litter decomposition rate, which caused soil nutrient deficiencies. (4) The RDA showed that the nutrient circulation of evergreen broad-leaved forest ecosystem was mainly affected by atmospheric temperature and soil C:N.
