Abstract

The evaluation ecological state of the urbanized territory are considered based on the integration of partial indicators characterizing assimilating organs of Scots pine, which forms natural frame of the Angarsk urban space. According to the results of measurements in the 2011—2012 years the range of values the damage index, the index fluctuating asymmetry and total content of heavy metals in the needles and the integral index corresponding to the permissible anthropogenic load, arising in urban environment where the pine trees assimilating organs grow and develop were defined. The results of calculation of the anthropogenic load actual value showed it exceeded by 45 % in comparing with the “normalized” value.

Keywords

scots pine needles, the damage index, the index fluctuating asymmetry, heavy metal content, the urbanized area, the integrative index, ecological condition.
