Through investigation on the impact of environmental factors(including dissolved oxygen,pH value,temperature and disturbance) and submerged plant on phosphate release from sediment,the impact factors of environmental factors affecting phosphate release,and submerged plant affecting phosphate release under different environmental factors have been analyzed.It can be concluded that dissolved oxygen,pH value,temperature and disturbance can affect phosphate release from the sediment,among which,both dissolved oxygen and pH value are the more important environmental factors;phosphate in lakes especially the shallow ones plays an important role in water eutrophication;and submerged plant play a key part in preventing the sediment from being stirred by environmental factors such as water pervasion,winds and so on;moreover,in the shallow lakes,it is of practical value to revive submerged plant like Myriophyllum spicatum L.in the sediment under the conditions with the greater disturbances in lake,for the control of phosphate release from the sediment.
