We analysed the taxonomical structure of three floras types: ruderal flora of towns, ruderal flora of small settlements and flora of the natural territories. It is revealed that anthropogenous transformation of flora is reflected in its taxonomical structure, incrasing the of concentration of types in ten leading families and changing their ratio in the range. With the increase of the degree of anthropogenic transformation of flora of the natural territories to ruderal flora of towns is the regular change of taxonomic spectra, which allows to consider these spectras as one of the indicators anthropogenic transformation of flora. The role of indicators dramatically changing its position in the taxonomic spectrum at the anthropogenic impact, perfom families such as Cyperaceae, Ranunculaceae, Rosaceae, Brassicaceae, Fabaceae и Chenopodiaceae.
