水体中的磷素主要来自外源磷的输入和内源磷的释放，目前内源磷释放已经成为水体富营养化中磷的主要来源，因此研究内源磷释放机理及其控制技术具有重要意义。文章介绍了沉积物循环机理，简述了沉积物磷释放的影响因素，溶解氧、水温和pH等因素对沉积物磷释放有很大影响。综述了当前控制沉积物释磷的常用技术手段，认为低成本高效率的化学修复技术具有良好的发展前景，疏浚技术与生态修复相结合的技术手段有可能成为今后控制沉积物磷素释放的发展方向。

Phosphorus in water is mainly from exogenous phosphorus and internal phosphorus .At present ,the release of internal phosphorus is becoming the main source of water eutrophication ,so that the research of the release mechanism and control technology of internal phosphorus is of great significance . The paper introduced the cycling mechanism of sediments ,and described the factors including dissolved oxygen ,temperature and pH value had great influences on the phosphorus release in sediments .It also reviewed the commonly used technologies controlling phosphorus release ,and considered that the low-cost and efficient chemical remediation technology had a good development prospect ,the combination of dredging and ecological restoration may become a developing direction of controlling phosphorus release in sediments .
