Assessment of the state of the urboecosystem by integral indicators of pine and soil cover

Abstract

Soil contamination due to the accumulation of heavy metals directly affects the biogeochemical composition, development stability (fluctuating asymmetry) of urban vegetation. To assess the condition of urbanized territories, monitoring is required, especially biological. This work shows an assessment of the stability of the development of populations of Scots pine growing in the urban environment, depending on the content of heavy metals in the soil cover, needles. The representativeness of the data obtained is confirmed by appropriate statistical processing. Higher values of integral indicators were found for all the territories examined, especially for the Central Park, which is characterized by maximum traffic load. The values of the fluctuating asymmetry index of pine needles reflect the elemental composition of the soil cover (Pb, Cd, Zn, Cu, Ni, Co Cr, Mn).
