摘　　要：通过对三峡库区底泥总氮、总磷（TN、TP）释放特性研究，分析了水溶液电导率对底泥TN、TP释放的影响及其原因，得出了水溶液的电导率在257～2012μs／cm范围内，对底泥TN、TP释放的影响曲线。同时说明了三峡库区底泥TN、TP对库区水质存在的危险性，为三峡库区富营养化治理提供参考。By experimental study on the total dissolved nitrogen （TN） ＆ total dissolved phosphorus （TP） release characteristics of bottom silt in the Three Gorges Region, the influence of electrical conductivity on the TN ＆ TP release of the bottom silt and the cause for it are analyzed. The curve of influence of the electrical conductivity in range from 257 μs/cm to 2012μs/cm on TN ＆ TP release of bottom silt is obtained. At the same time, it is pointed out that there is latent danger from the TN ＆ TP of the Three Gorges bottom silt to the water offering a basis for eutrophication treatment of the Three Gorges.
