Аннотация: In recent decades, there has been broad worldwide discussion on the impact of climate change and anthropogenic and biogenic factors on tree growth. Most studies have focused on annual growth in natural stands, while little attention has been paid to urban forests and the findings are highly controversial. Urban vegetation worldwideПоказать полностьюis influenced by the "urban heat island" effect, i.e. air temperature differences between city centers and neighborhoods. The paper presents the results of a comparative assessment of growth dynamics of four urban forest stands and four rural forest stands (outside the agglomeration of Ekaterinburg) under changing climate conditions. Over the last fifty years, a continuous trend for air temperature increase has been observed in both urban and rural areas. Nevertheless, a higher average annual temperature (by 0.9 °C) and the temperature of the growing season (by 0.9 °C) are characteristic of the climate of the city. Moisture regimen in the compared territories do not differ and no apparent trend has been observed. It was shown that the long-term dynamics of radial growth of pine trees in urban forest parks and natural landscapes was synchronous. Only 11 years out of 50 were found to yield statistically different growth values in urban and natural habitats. However, a more prominent response of radial tree growth to climatic variables was observed in urban areas. Thus, despite the warmer conditions in the metropolis, no differences in the dynamics of radial growth between urban and rural populations of the Scots pine were found, except for individual years with extreme climatic events. © Siberian Federal University.
