摘　　要：作为外来种,互花米草(Spartina alterniflora)对入侵地的生态系统产生了较强的干扰,但同时高生物量的互花米草也是一种潜在的生物质能源。发展生物质能是充分利用互花米草资源并控制其恶性扩张的较为有效和实用的途径,具有生态和经济双重效益。本文总结了互花米草生物质能的利用潜力,其表现为时间与空间上的生物量资源优势、高效的光合作用机制与高生产力、高贮能、较高的碳水化合物、蛋白质和脂肪储量以及不占用耕地等;同时介绍了互花米草生物质能开发利用现状,并指出互花米草生物质能的开发与利用有着光明的前景。As an exotic invasive species, Spartina alterniflora Loisel strongly disturbs the structure and function of native ecosystems, but at the same time, it is also a potential bio-energy source due to its high standing biomass. To develop this bio-energy source is an efficient and useful way in fully utilizing the resource of S. alterniflora while control its crazy expansion, being of both ecological and economic significances. In this paper, the utilization potential of S. alterni- flora as a bio-energy source, including the superiority of its biomass resources at both temporal and spatial scales, its high-efficient photosynthetic mechanisms and high productivity, its high energy storage and higher contents of carbohydrate, protein and fat, and the un-occupying of crop land, etc. , was summarized, and the present situations about the exploitation and utilization of S. alterniflora were introduced. It was pointed out that the exploitation and utilization of S. alternifloral as a bio-energy source would have a promising prospect.
