Preliminary Discussion on Phytoremediation of Eutrophication Repair in the Three Gorges Reservoir Area

After water storage of the Three Gorges reservoir,eutrophication appeared in local waters,which brought certain threat to water environment in the Three Gorges Reservoir area.Therefore,a low input and efficient technique should be put forward.Phytoremediation technology with low-cost,good economic returns,landscaping and other features had obvious advantages in many governance measures for eutrophication.Due to the different characteristics of different plants,restoration techniques included floating island,artificial wetlands,and restoration of aquatic vegetation components.According to the characteristics of different regions of the Three Gorges Reservoir area,reasonable selection of treatment had good effect on eutrophication of the reservoir water management and had broad prospect.
