In this dissertation, EISCAT radar observations and computer numerical simulation methods are involved to study the climatologic characteristics of polar ionosphere and their mechanisms, as well as the polar ionospheric responses to magnetospheric particle precipitation and convection electric field. Then, with the help of the numerical computation, the EISCAT data are employed to invert the energy spectra of auroral precipitating particles and their responses to magnetic storms and substorms.
