The changes of the phosphorus forms in the sediments and gap water of the different layer sediments by submerged plant has been studied using the submerged plant Hydrilla verticillata culturing in homology area sediments and soil.The rule on the transferred of the phosphorus forms in different layer sediments and submerged soil by submerged plant has been studied using were open out.The different layer soil results show prone to transferred of phosphorus;The results indicate that the main transferred of phosphorus on the soil great than the comparative level on the alimentation sediments

the submerged plant Hydrilla verticillata can to boost transferred inorganic phosphorus in the superstratum sediments to overlying water and boost transferred organic phosphorus in the substrate(layer take on root tip) sediments;Effects of transferred of the phosphorus in the substrate sediments less than soil

the superstratum sediments great than soil by submerged plant.Effects of changes of the phosphorus forms in the gap water of the sediments by absorb effect and circumstance effect of the Hydrilla verticillata

effects of changes of the phosphorus forms in the gap water and the sediments great than soil by Hydrilla verticillata.
