Deterioration of park green plantation in Barnaul, as well as other urban areas, is the result of anthropogenic pollution and worsening ecological situation in the city. One of the promising methods of integrated estimation of the environmental quality and life activity of grassy plants is to value the state of the living organisms on the development stability of morphometric characters. The article presents the results of studying morphometric parameters of field bindweed leaves (Convolvulus arvensis L.) growing in the different anthropogenic load areas (highway and city parks, and the area of Barnaul melange factory). Ecologically important morphological parameters of the plant’s leaves (length and width), which allow us to give a reliable characteristic of the species habitat conditions were revealed. The morphometric parameters of the leaf blade — leaf width, leaf length — are sensitive to air pollution and display the quality of the environment. Decrease of the morphometric parameters of the leaf blade could be attributed to morphological adaptations allowing field bindweed to withstand a negative impact of technological factors (pollution by exhaust gases of vehicles, dust, trampling, etc.).
