Abstract:: The changes of soil carbon, nitrogen and phosphorus in estuarine wetland significantly affect the productivity of wetland ecosystem. A typical plant community was selected to take soil and plant samples in the estuary of Luanhe River. The nutrient contents of samples were determined and analyzed. The results showed that the nutrient contents of the above-ground parts and underground parts of different plant communities decreased in the order: C > N > P; there was a certain difference in soil nutrient contents between different plant communities. The variation ranges of soil carbon, nitrogen and phosphorus contents were (3.8±0.44)~(10.52±0.6) g/kg， (0.99±0.27)~(2.24±0.51) g/kg， (0.99±0.27)~(2.24±0.51) g/kg, respectively. The soil nutrient contents in the study area were lower than those of the national average values. Stoichiometric ratios of plants decreased in the order: C:P > C:N > N:P; stoichiometric ratios of soils decreased in the order: C:N > C:P > N:P, which indicated that the soil organic matter decomposition rate was fast, nitrate leaching risk and nitrogen mineralization degree were high. Therefore, increasing the content of soil organic matter and nitrogen fertilizer can improve the productivity of wetland ecosystem in this area.
