Research Abstract	We made researches in order to get the relation between the air temperature and the land use. Analysis for this report was made by using data from the west of Hokkaido, Tokyo, Nagano, etc, and a regression analysis between the temperature and the land use. In this analysis, the land use is classified into four kinds (1. artifical area, 2. agriculturally cultivated area, 3. forest land, 4. water area) and the height above the sea level is also considered. The study led to the following result. 1) The artificial area always tends to raise the air temperature and the agriculturally cultivated area lower. 2) The influence of the forest land on it is small. 3) The water area intensely influences on the minimum temperature. 4) The height above the sea level makes the temperature lower, approximately 0.6ﾟC per 100 meters rise.
