【 摘 要 】
The changes of nitrogen and phosphorus release with time from sediment in Taihu Lake after ecological dredging were tested in laboratory. Experiment results showed that in a simulated environment of Taihu Lake, dredging was effective to reduce the endogenous pollution release, and the effect weakened gradually along with time. When the velocity of flow increased, nitrogen and phosphorus release intensity increased, so did the largest nitrogen and phosphorus emission. Considered the resedimentation, the release of nitrogen and phosphorus were similar in the area of five years after dredging and just dredging. Re-dredging should be considered.
