大型海藻对富营养化海湾生物修复的研究进展

PROSPECT FOR BIOREMEDIATION OF LARGE-SIZED SEAWEED CULTIVATION IN EUTROPHIC BAYS

近年来,我国诸多海湾富营养化严重,海湾赤潮和大规模的养殖生物病害频繁发生,海湾生态系统严重失衡。海带、裙带菜、紫菜、龙须菜等大型经济海藻,生物量大、生产力高,在生长过程中能大量吸收C、N、P等营养物质,栽培大型海藻是吸收、利用营养物质,防治富营养化的有效措施之一。本文综述了规模化栽培大型海藻对富营养化海湾生物修复的研究进展。

Eutrophication has become a serious problem in most of the bays in china. This may cause red tides and animal diseases, and break the balance of the bay ecosystem. Some cultivated seaweeds such as Laminaria japonica, Undaria pinnati fida , Porphyra yezonesis and Gracilaria lemanea formis are of high productivity and may absorb large quantities of C, N, P, and produce large amounts of 02. Scholars believe that large-scale cultivation of seaweeds could be a good solution to the proplem of eutrophication due to their capability of removing nutrients.
