摘      要：Aims Dune building processes are affected by interactions between the growth of ecosystem engineering dune grasses and environmen-tal factors associated with disturbance such as sand burial and sea *** investigating how species interactions influence dune community structure and functional trait responses in high abiotic stress environments is *** investigated how spe-cies interactions influence the functional trait responses of three dominant dune grasses to common abiotic *** We performed a multi-factorial greenhouse experiment by plant-ing three common dune grasses(Ammophila breviligulata Fern.,Uniola paniculata *** Spartina patens Muhl.)in different interspecific combinations,using sand burial and sea spray as abiotic *** burial was applied once at the beginning of the *** spray was applied three times per week using a calibrated spray *** functional trait meas-urements(leaf elongation,maximum root length,aboveground biomass and belowground biomass)were collected at the end of the *** experiment continued from May 2015 to August *** Findings Species interactions between *** and *** negatively affected dune building function traits of ***,indicating that interactions with *** could alter dune community ***,*** had a negative interaction with ***,which decreased *** functional trait responses to abiotic *** all species occurred together,the interactions among species brought about coexistence of all three *** data suggest that species interactions can change traditional functional trait responses of dominant species to abiotic stress.
