In order to clarify the effects of crabs activities on soil carbon,nitrogen,and phosphorus concentration and its ecological stoichiometry characteristics,the soil carbon,nitrogen,and phosphorus concentration and its ecological stoichiometry characteristics under effects of crabs activities in different flat of Minjiang River estuarine wetlands were measured and analyzed. The results showed: the averaged soil carbon,nitrogen and phosphorus concentration were( 13.32±0.66),( 1.51±0.05),( 0.70±0.05) g·kg~(-1) a...
