The purpose of this study is to clarify the differences on the formation of thermal environment in Higashihiroshima city among three area types, such as Urban, Rural, and Around Irrigation Pond. The main measurements were carried out by the system of weather observation installed at Hiroshima University, ground surface temperature, and by self recording loggers of temperature and humidity in 24 shelter instruments spread in the city. In addition, several methods were taken for the analysis and three results were obtained as following. 1) By the temperatures measured in the 24 shelter instruments, the tendencies of the formation of temperature in each season were clarified. Especially on the analysis for the difference of the temperatures of Urban and Rural with considering the global solar radiation, the different tendencies of the formation of temperature in each area were grasped. 2) The tendency of artificial surface ground, which works as heat source toward the surrounding temperature, was grasped by multiple linear regression analysis based on the surface ground conditions. 3) The influence of the wind passing through irrigation pond to the thermal environment around was clarified by the detailed measurement at Shitami pond. The water surface works as cooling source in the daytime of spring and summer but works as heat source in the nieht time of autumn and winter.
