Özet

Urban green infrastructure has a major role in improving the outdoor thermal environment. The aim of this study is to examine the effect of different tree groups on the outdoor thermal environment in Elazığ province of Türkiye. Air temperature, relative humidity, mean radiant temperature (Tmrt), and wind speed parameters were measured hourly with the weather forecast device. In this study, where ENVI-met BIO + Science 5.6.1 software was used, eight different landscape scenarios were prepared according to the physical characteristics of the vegetation. Sixteen simulations were carried out for summer and winter periods. The reliability of the simulation model was also tested through accuracy analysis. The existing vegetation in the study area showed a cooling effect of 0.4 °C compared to its surroundings during the summer period. A very small cooling effect was detected in scenarios where coniferous trees were used. The best cooling effect in temperature was obtained as 1.6 °C in the scenario where medium-diameter deciduous trees were used. In the relative humidity analysis, the highest value was obtained from the scenario where medium-diameter deciduous trees were used. In the analyses conducted for the summer and winter periods, the scenario in which the lowest Tmrt value was obtained was the scenario in which medium-diameter deciduous trees were used. The cooling effect of deciduous trees was determined to be greater than that of coniferous trees in summer. Medium-sized trees have a greater cooling effect than short and tall trees. It is envisaged that the results of this study will provide guidance for urban planners and designers working in urban renewal/transformation areas in reducing the urban heat island effect.
