摘要: Abstract Since microclimate regulation is one of the most important services vegetation that directly perceived by urban population, many studies aimed to evaluate and map this service on different spatial scales. Most investigations focused modification only parameter, namely reduction air temperature. However, it state thermal sensation, health well-being are influenced more atmospheric parameters, including humidity, wind velocity three-dimensional short- long-wave radiation environment as well. This necessitates assessment effect components separately. With above mentioned objective, paper presents initial results a investigation series carried out in Szeged, South-East Hungary. Systematic on-site measurements were with pair special human-biometeorological stations 20 clear summer days 2015 order reveal small-scale climate potential single trees environment. Five healthy, mature selected for analysis, without disturbing (additional shading) any other or artificial objects. We compare separately median values main parameters – temperature, relative well from upper lower hemisphere measured under canopy trees, sun. Our demonstrate all five investigated tree specimens have significantly greater impact budget, while temperature humidity rather small. Inter-species differences seem be small warmest hours day, may attributed dimensional canopy-characteristics. During development ecosystem indicators would advisable use integrated indices which take into account meteorological influence considerably human comfort.
