The present study purposed to survey temperature and humidity according to land use patterns in Chungju, a medium-size city under urbanization, and to find the causes and intensity of the heat island in the city. The results of this study are as follows. The highest temperature was distributed in the commercial area regardless of season. However, the Jungang park surrounded by the commercial area formed a cool island, showing relative lower temperature than its surroundings. The distribution of the lowest temperature was high in green areas and areas around Lake Hoam. As to humidity, the distribution was almost coincident with that of temperature regardless of season. That is, the area of the highest temperature showed the lowest humidity and the area of the lowest temperature showed the highest humidity. Centering on the commercial area, the relation among the wind direction from its outer circumference, distance from the area, and the highest and lowest temperature was affected relatively more in the leeward than in the windward regardless of season. In addition, when there was little influence of the wind, the temperature of the commercial area was relatively higher than its neighboring residential area 1 and 2 regardless of season, but not higher than the residential area on the leeward affected by the wind. The daily variations of temperature and humidity according to land use pattern were large in order of bare grounds, grasslands, water surfaces and planted areas. |
