Impact of Vegetation on Microclimate in Different Layouts of Built- Up Areas in Urbanised Environment of Nitra Municipality in Spring Period

Vegetation has an important role in urbanised environment, as its functions enhance the quality of life in towns. Its structure shades anthropogenic surfaces, limiting the accumulation of direct solar radiation and subsequent emission of converted thermal radiation. This represents its potential in reducing the urban heat-island effect. It increases relative air humidity and reduces air temperature. Besides microclimatic function, vegetation also has health, aesthetic, recreational and other functions. Research is focused on comparing microclimatic factors (air temperature, relative air humidity, surface temperatures, airflow) between two monitored areas with different vegetation structures. Areas represent an area with vegetation cover (particularly tree plants) and an area without vegetation, respectively with minor representation of vegetation. Microclimatic conditions are also compared for four different types of built-up areas in the town of Nitra, which are represented by a characteristic street.
