摘要
通过室内模拟实验,分析了环境因子(温度、pH、扰动)对底泥内源磷释放的影响及原因。实验表明:温度升高和水的扰动有利于底泥磷的释放;中性条件磷的释放速率较慢,偏酸或偏碱条件都有利于底泥磷的释放。
Based on the releasing experiment of phosphorus （P）, the thesis analyzed internal P release characteristics under different environmental factors （such as temperatures,pH values,disturbance）.The results showed that： temperature increasing and disturbance of water cause the release of P from silt into overlying water; The content of P releasing from the silt reach the lowest level when the overlying water is neutral, high pH or low pH can increase the content of P releasing from silt.
