Abstract

Ecological stoichiometry has been widely applied to ecosystem management around the world, mainly through analysis of carbon(C), nitrogen and phosphorus (P). Ecological stoichiometric characteristics have important imply meaning on key processes and mechanisms of protection, restoration and reconstruction of urban wetlands. This study selected the Huoshaogou urban wetland of Xining city as a case study. On the basis of experimental analysis data, we analyzed the characteristics of C, N and P contents and the inner coupling relationships among the C, N and P in sediments and plants of this wetland. Results indicated that: 1) The contents of the C in sediments are high and the C, N and P contents in the plants are relative low. N and P in the sediments are, respectively, mainly at "level 1" and "level 4" in national soil nutrient classifications.2) Limiting factors of plants growth: P may limit the plants growth in 1-5 cascades, N may limit the plants growth in 6-9 cascades; 3) There are statistically significant correlations between C and C/P in the sediments and N/P in the plants P<0.05 . The current results may provide theoretical support for the management of the Huoshaogou wetland.
