摘要

A strong reduction of agricultural lands is observed now in Russia. The area of all the croplands in Russia was equal to 117050000 ha in 1990, while it was only 84753000 ha in 2001, i.e., it was reduced almost by 35 mln ha [1]. Changes in vegetation occur on these areas. Along with segetal plants (typical field weeds), plants from natural cenoses start to become abundant; these are inhabitants of forest edges and meadows adjacent to croplands. Ruderal species from some garbage sites, edges and talusof routes are also invading former fields.
