There are less researches in the influence of disturbance of endogenous phosphorus release in sediment. The correlational analysis only takes the disturbance as one of the many factors in influencing the phosphorus release. It hasn’t been able to make a deeper discussion from disturbance itself. In this paper, HAOHE River of Nantong, China is selected as study area. The whole process of disturbance is simulated in the laboratory. Disturbance intensity, time and depth is respectively simulated and analysed their effects on endogenous phosphorus release in sediment. The result shows that the external disturbance can significantly increase the release of endogenous phosphorus in sediment. From the time series of the experimental results, the release of phosphorus is not increased with the increasing time. The depth experiment has showed that the maximum phosphorus release is closest to the sediment and the closest to the water surface, while the phosphorus release in the position of middle depth is less.
