Abstract: | Data on interstellar diffraction and refraction scintillation of pulsars are analyzed. Comparison between theory and the observational
data shows that two types of spectra for electron density fluctuations are realized in the interstellar medium: pure power
law and piecewise with a break. The distribution of turbulent plasma in the Galaxy has a three component structure. Component
A is diffuse and it is distributed outside of the spiral arms of the Galaxy. Component BI is cloudy and associated with Galactic
arms. Component BII is extremely nonuniform and associated with HII regions and supernova remnants. The origin of the interstellar
plasma turbulence is considered, and possible sources of turbulent energy are discussed. The contribution of supernova bursts
in the interstellar gas ionization and generation of turbulence are analyzed among other factors.
