In part 3, the simulation study of the earth surface heat budget on the annual and diurnal variation was described. The earth suruface heat budget is generally consisted of two elements, namely, natural heat and artificial heat released. In this paper, the case study of Osaka district is described. The study area are Osaka prefecture (about 1856km^2), Osaka City (about 206km^2) as a developed region and Sennan district (about 200km^2) as an undeveloped region. The latter two are included the former. The natural heat and the artificial heat released in each district are analyzed in connection with the land uses. The monthly mean erath surface temperature of August is 28.0℃ in Osaka prefecture, 30.4℃ in Osaka City, 27.4℃ in Sennan district. The temperature in Osaka City is higher about 3℃ than in Sennan district. The artificial heat relesed was 174.2×10^12kcal/year in Osaka prefecture, 39.3×10^<12>kcal/year in Osaka City and 7.9×10^<12>kcal/year in Sennan district (1970-1974). Though Osaka City and Sennan district are almost equal area, but the artificial heat released is very different. On the heat budget's component, the sensible heat and the artificial heat released in Osaka City are much larger than in Sennan district, and the latent heat heat in Sennan district is larger than in Osaka City. The heat flow of the nature changes remarkably according to an urban developement.
