摘　　要：利用HYCOM模式在台湾海峡附近一个断面处1 a的温盐流输出结果,计算了南海和东海之间通过台湾海峡输运的水体及热盐通量。结果表明:夏季的水体通量和热盐通量最大,秋季的水体通量和盐通量最小,而春季的热通量最小,3个通量均呈现出明显的季节变化。水体通量和热盐通量的季平均值分别为1.14 Sv,1.1×1014W,3.97×1010 g/s。The fluxes of mass, heat and salinity between the South China Sea and the East China Sea via Taiwan Strait were estimated using hydrologic and current data of one year in a section of Taiwan Strait from HYCOM model. The following conclusions can be obtained. The three fluxes are all reach maximum in summer while the time they reach minimum is not coincident： autumn for the mass and salinity fluxes and spring for the heat flux. Despite of which, the results represent significantly seasonal variations for the three fluxes. The year-averaging values for mass flux, heat flux and salinity flux are 1.14 Sv,1.1×10^14W,3.97×10^10 g/s.
