Carbon,nitrogen and phosphorus content and its ecological stoichiometry ratios of paddy field soil-plants in the Min River estuary were studied.The results showed： soil carbon,nitrogen and phosphorus were 5.72-13.41,0.47-0.82,0.33-0.89 mg·g-1 and the averaged values were 9.50,0.62,0.56 mg·g-1.Its C/N,C/P and N/P ratios were 12.18-16.39,15.07-24.34,0.92-1.55 and the averaged values were 15.05,17.88 and 1.20.Plant carbon,nitrogen and phosphorus were 28.62-38.99,0.65-1.52,0.13-0.32 mg·g-1 and the averaged values were 35.21,1.19,0.25 mg·g-1.Its C/N,C/P and N/P ratios were 24.54-44.10,94.05-258.93,2.13-10.55 and the averaged values were 32.11,160.07,5.47.Soil carbon and nitrogen were lower than plant,but phosphorus was higher.C/N,C/P and N/P ratios in soil appeared to be lower than those in plants.
