This study aims at examining the correlation between air temperature and urban structure such as land cover. For this, it measured summer air temperature by using data log type thermometer installed the inside of instrument screen, in the 9 points of elementary school in Haeundae, Busan. The accomplished results of this study are followings. 1) As altitude goes up 100m, air temperature drops to $0.6{sim}1.0^{circ}C$. 2) As building coverage ratio increases 10%, air temperature increases $0.3{sim}0.4^{circ}C$. 3) As floor space index increases 100%, air temperature increases $0.4{sim}0.5^{circ}C$. 4) As artificial coverage ratio increases 10%, air temperature increases $0.1{sim}0.2^{circ}C$. 5) As natural coverage ratio increases 10%, air temperature decreases $0.1{sim}0.2^{circ}C$.
