INFLUENCE OF URBAN ENVIRONMENT ON MORPHOMETRIC PARAMETERS OF BIRCH LEAVES (ON THE EXAMPLE OF UST-KAMENOGORSK)

   Environmental quality assessment is relevant for the detection of pollution. The silver birch due to its biological-ecological characteristics is often used in the creation of protective forests on the territory of large industrial centers of our region . Morphometric analysis of birch leaf plate, carried out by methods of fluctuation asymmetry and measuring the area of the leaf plate, revealed the change of leaves from the impact of anthropogenic load. Leaf samples were taken at 4 test sites. Calculation of asymmetry fluctuations was made by the method of M. Zakharov. On the test sites in terms of asymmetry of leaves exceeds the conditional norm and the area of the leaf surface depends on the degree of load on them. The obtained results show that in the urban environment the plantings were contaminated. The fluctuating asymmetry method can be used as one of the methods for bioindication of the urban environment. The analysis and assessment of the impact on the environment, indicating the effectiveness of this method.
