THE ROLE OF LAND-USE PARAMETERS IN THE SPATIAL DEVELOPMENT OF URBAN HEAT ISLAND IN SZEGED, HUNGARY

摘要

The modification effect of urbanization on local climate is most obvious in case of temperature, which phenomenon is the so-called urban heat island (UHI) or urban heat archipelago if the structure is multi-cellar. Statistical modeling may provide useful quantitative information about the structure as well as spatial and temporal features of the maximum UHI intensity by employing different urban surface factors (Oke, 1981, 1988; Kuttler et al., 1996). In our case these factors are the built-up ratio, the sky view factor and the building height. The selection of the parameters is based on their role in small-scale climate variations (Golany, 1996). The purpose of this study is to determine influences of the urban surface factors on the patterns of urban-rural temperature differences quantitatively in the non-heating half years.
