The effects of removing the pollutants by aquatic plants in ihe resloration zone in the norlheasleni of l)i-anohi Lake were invesligated in ihis paper. The volume of the pollulanls removed from the lake by the aqualir planl harvesting and the sedimention had also been estimated. The result showed that the restoration zone had a remarka-hle accelerative effecl on silting-up of the resloration. In the whole resloration zone,the average seilinienlation flux was 118.9 kg/(m²? a). There fore it means about 120 g/(m²? a) TN,70 g/(m²?a) TP ami 1080 g/(m²?a) TOC can be removed from lake. The situation of ihe sedimention in ihe zone has been improved a U't, as ihe roii-centration of TN and TOC in the surface sedimenl was 4 times as high as before. The amount of harvesftMl aquatic* plants was aboul 113000 kg in 2002,which means that 30.0 g/(m²?a) TN and 4. 8 g/(m²?a) TP were vemove;! from lake. Therefore, il can be concluded that the restoration of aquatic plants in the littoral may be used as an effective engineering measure for lakes pollution control especially the algae bloom control at the norl}i(jasU?rn Diaiuhi Lake, and in other severely polluted waler bodies.
