海草生态系统是众多海洋生物的重要栖息地和育苗场所,具有较高的生产力和生物多样性,在渔业资源和海岸带保护等方面具有重要的生态功能和服务价值。海草是一类分布在温带、亚热带和热带浅水域的单子叶草本植物,一般生活在较柔软的潮下带滨海区域,在全球有广泛分布。海草是海洋中唯一开花的被子植物,在水中完成生活史。成片的海草构成海草床,亦有“海底草原”之称。海草床具有极高的生产力,与红树林和珊瑚礁并称为三大典型的海洋生态系统。海草生态系统的年初级生产力约为500~1000克·碳/平方米,

Seaweed ecosystem is an important habitat and nursery area for many marine organisms. It has high productivity and biodiversity, and has important ecological functions and service values ​​in fishery resources and coastal zone protection. Seaweed is a class of monocots distributed in temperate, subtropical and tropical shallow waters. They generally live in the softer subtidal coastal area and are widely distributed in the world. Seaweed is the only flowering angiosperm in the ocean that completes its life in water. Into a piece of seaweed seagrass beds, but also “” seabed prairie "said. Seagrass beds have high productivity, together with mangroves and coral reefs, as the three most typical marine ecosystems. Annual productivity of seagrass ecosystems is about 500 to 1,000 grams per cubic meter of carbon per square meter,
