Other Abstract Solar Extreme Ultraviolet (EUV) plays an important role in space weather research and forecasting. The E_(10.7) index is the integrated EUV energy flux at the top of the atmosphere. Solarv2000 model combines the best of empirical and physics-based models to provide a wide variety of solar irradiance products for science and engineering applications, including E_(10.7) integrated EUV flux etc. In this paper, the physics significance of the E_(10.7) index is described, and a new computation method of E_(10.7) index is also described in details. Double channel solar irradiance flux were used to compute the E_(10.7) index. At first the experiential coefficients were obtained based on the empirical expression and historical solar irradiance data picked up from the Solar 2000 model. Then the new method was applied to solar irradiance flux data from the year of 2000 to 2005, and successfully yields the E_(10.7) index. The differences between the compute result and the result from Solar 2000 model were calculated. The comparison results show that the mean relative deviation is within 10% with a maximum deviation less than 20%.
