摘　　要：前言在我国海涂中被日潮淹没的中、低潮带,天然生长的高等植物种类比较贫乏,分布面积也较小,许多中低潮带海滩为光滩裸地。为了绿化海滩、保护海滩,提高海滩生态系统的初级生产力。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·m^(-2) and 2×10~7J·m^(-2), while these of Aeluropus-Imperata community are 121.92g·m^(-2) and 2.34×10~6J·m^(-2); the harvestable crude protein and fat contents of Spartina vegetation are 84.28g·m^(-2) and 32.14 g·m^(-2), while these of Aeluropus-Imperata community are 8.64g·m^(-2) and 2.08g·m^(-2), respectively. Therefore, Spartina vagetation has greater ecological and economic benefits than Aeluropus-Imperata cemmunity.
