【Objective】How matter recycling matches ecosystem services is always one of the central concerns of the research on ecology, and C:N:P ecological stoichiometry has been an effective tool to link chemical processes on the molecular level with ecological processes in ecosystems. The knowledge about how carbon, N and P is distributed in wetland soils and whether there is a "Redfiled-type" C:N:P ratio in regional or global wetland soils is the basis for understanding fate of carbon, nitrogen and phosphorus and modeling matter circulation in wetland ecosystems. Objectives of this study are to examine whether there is a consistent C:N:P ratio in wetland soils of China and to find its potential influencing factors. 【Method】Based on the data of carbon, nutrient contents, soil properties, vegetation, meteorology and C:N:P ratios of wetland soils of 119 marshes or wetlands published in the “Journal of Marshes of China”, ecological stoichiometric characteristics of C:N:P ratios on a regional scale and their potential affecting factors were analyzed with the mathematical statistics. 【Result】Results show that the average C, N and P content in the wetlands of China was 22.93%, 0.76% and 0.16%, respectively; the average C:N, C:P and N:P ratio (mole ratio) was 18.22, 245.22 and 13.60, respectively, all higher than their respective ones in the soils of the country and the globe; and the average C:N:P ratio was 245:13.6:1. The C:N, C:P and N:P ratio in organic soils was higher than their respective ones in mineral soils. No significant difference was found in soil C:N:P between meadow, peat moss and forest wetlands; However, significant differences were found between inland freshwater, inland saline and tidal wetlands, with the inland freshwater wetlands being the highest and the tidal wetlands the lowest in C:P and N:P ratios, but. no difference in C:N was between the two. Overall, C:N, C:P and N:P ratios were the highest in inland freshwater wetlands and the lowest in tidal wetlands. Pearson analysis shows no significant pairwise relationship was found between the three elements, which implies that there is no “Redfield”-type ratios in the wetland soils of China. Wetland ecosystems were more affected by P than the other soil nutrients. No significant difference in C:N ratio was found between climate zones, but a decreasing order of Tropical Zone > Temperate Zone > Plateau Temperate Zone > Warm Temperate Zone >Mid-subtropical Zone > Northern Subtropical Zone was, while C:P and N:P ratios differed significantly between climate zones, which followed an order of Plateau Temperate Zone > Temperate Zone > Mid-subtropical Zone > Tropical Zone > Warm Temperate Zone > Northern Subtropical Zone in C:P ratio and an order of Plateau Temperate Zone > Mid-subtropical Zone > Temperate Zone > Warm Temperate Zone > Tropical Zone > Northern Subtropical Zone in N:P ratio. Correlation analysis shows that altitude, temperatures (annual mean temperature, mean temperatures in January and July, and active accumulated temperature) and pH are the three main factors determining C:N:P ratios in the wetlands of China. 【Conclusion】In conclusion, C:N:P in the wetland soils of China are highly affected by soil types and climate conditions, and little by plant vegetation. Taking into account the extremely significant correlations of altitude with C:P and N:P, altitude is deemed to be the decisive factor of C:N:P ecological stoichiometry of wetland soils.
