Introduction
[2] Coniferous, deciduous and tropical forests cover more than 40% of
the land on the Earth. About 70% of the steppe regions are
covered by serials, fruit gardens, and cotton, coffee and tea
plantations. Therefore development of models making it possible
to estimate qualitatively and forecast quantitatively
electromagnetic field parameters in the Earth-ionosphere
waveguide at the presence of the vegetation cover is a quite
important problem.
