| Abstract: |
| In recent years, due to the process of eutrophication in sea water, the sediments in the intertidal flats have been eutrophicated. The biodiversity of the tidal flats and various important physical and chemical parameters such as dissolved oxygen capacity have declined significantly. Meanwhile, levels of ammonia nitrogen and nitrate nitrogen have increased significantly, resulting in habitat degradation in the tidal flats. Several studies have been carried out on bioremediation to restore the ecological environment of the intertidal flats. This article summarizes the current situation of eutrophication in the tidal flats; reviews the principle, characteristics, and consequences of the various bioremediation methods; and compares the merits and demerits of these restoration techniques. The key points of application of bioremediation for eutrophicated intertidal flats are also summarized, and future research directions of bioremediation in applied ecology and environmental protection are put forward. |
