Abstract:In order to compare the effects of plants on controlling sediments pollution in Fubao Bay of the Dianchi Lake, suspended matter sedimentation was carried on into plant areas,including submerged plant and emerged plant, and no-plant area by using particulate trap. In the process of on-spot research ,suspended matter sedimentation fiux of different areas was analyzed, particulate resuspension flux of different aquatic plant reparation areas was compared. Sediment resuspended flux, nitrogen release and phosphorus release of aquatic plant reparation areas were estimated. It was found that suspended matter sedimentation flux of no-plant areas was obviously higher than aquatic plant reparation areas. Estimation results indicated that sediment resuspended flux, nitrogen release and phosphorus release of in-engineering was the percent of 15.71%、13.30% and12.44% to the same areas out-engineering during 97days. The more effects of reducing sediments resuspension was submerged plant.
