本研究通过对磁湖底泥氮释放的特性进行实验室静态模拟实验,测定不同温度对磁湖底泥中氮释放量的影响。结果表明,温度升高时,底泥中NH3-N、TN释放通量增大,NO2-N和NO3-N释放通量减小。磁湖底泥的TN释放通量为-120到-25mg/m^3 d,NH3-N、NO2-N和NO3-N和TN释放通量基本呈负释放,说明磁湖大部分氮元素沉积到底泥中。本研究为探讨磁湖水质的改善提供相关的依据,并为以后关于磁湖的治理研究提供一定参考。

According to nitrogen releasing characteristics of sediment from Cihu Lake, this paper studies the impacts of tem- perature on nitrogen releasing capacity by static simulation. With the increase of temperature, release flux of NH3 - N and TN increased, while that of NO2 - N and NO3 - N decreased. The release flux of NH3 - N, NO2 - N, NO3 - N and TN are basically negative, which indicated that most of the nitrogen elements are remained in the sediment, causing serious eutrophication. This study provides foundations to improve the water quality of Cihu Lake, providing references to manage and research of Cihu water.
