Comprehensive assessment of the decorative effect of elm trees in an urban environment

This article provides the development of a methodology for assessing the decorative effect of elm trees, taking into account the complex influence of urban environmental factors. The key factors of decorativeness are analyzed, indicating that the decorative qualities of elms are most significantly influenced by: the number of green spaces, the level of dust in the air, the uniformity of species and the degree of morbidity, as well as aspects such as biology (B), ecology (E), landscape (L), care (C), social factors (S) and cultural innovation (H). These parameters became the basis for the creation of a mathematical model of decorativeness (D). The tested results are shown and evaluated in the study areas of two cities (Saratov and Engels) with different traffic intensity. To enhance the decorative effect, it is proposed to improve the care of trees on streets with high traffic intensity; replace damaged trees with resistant Ulmus species; regularly monitor soil conditions and pollution levels.
