Abstract
There are some cases of urban heat island impact on the thermal environment in medium scale city, although the mechanism of the mega city has been identified by several researchers. This paper examined the impact of land use and land cover on the thermal environment through an analysis of the observed ambient temperature at twelve points with the same condition. As a consequence, it was shown that one of the most significant causative factors of temperature increase is decrease of green area and increasing of medium and high building and impervious surface. This result implied that vegetated zones should be maintained in urban areas in order to realize sustainable urbanization.
