In our views, the region of the CMI, near the ionosphere of Saturn (1 Saturn radius above the polar area), is regarded as the same area as the Saturn's Kilometric Radiation Source.In this paper, we deduce that the KHI will appear before 11 LT (Saturn's Local Time), the Alfven wave will take 383 min to reach Saturn, the sunward magnetic line will bend almost 80°. Finally, we get the distribution of SKR source. It locates from 7～9 LT at a relatively lower latitude to 18 LT at the eveningside.
