Abstract: The sclar radiation absorption, aboveground biomass and caloric and nutrient contents of artificial Spartina alterniflora vegetation are studied and compared with these of natural Aeluropus-Imperata community. In August, the solar radiation absorption of Spartina vegetation is 90.5%, while that of Aeluropus-Imperata community is 71.8%; the biomass and caloric contents of Spartina vegetation are respectively 1075.03g穖-2 and 2?107J穖-2, while these of Aeluropus-Imperata community are 121.92g穖-2 and 2.34?106J穖-2; the harvestable crude protein and fat contents of Spartina vegetation are 84.28g穖-2 and 32.14 g穖-2, while these of Aeluropus-Imperata community are 8.64g穖-2 and 2.08g穖-2, respectively. Therefore, Spartina vagetation has greater ecological and economic benefits than Aeluropus-Imperata cemmunity.
