This study analyzed weather characteristics for each biotope type and influential factors on outdoor temperature in the summer when thermal contamination is at its worst targeting Daedoek-gu, and suggested a management plan in thermal comfort aspect by using a bioclimatic chart. Impermeable area ratio for each biotope type was shown in orders of industrial area biotope(94.80%)＞commercial area biotope(92.20%)＞low floor residential area biotope (85.75%)＞high floor residential area biotope(76.02%)＞river biotope(2.35%)＞forest biotope(0%). Meteorological element analysis was divided into daily maximum and daily minimum and conducted, and outdoor temperature, humidity, wind speed, globe temperature, and surface temperature were measured. Outdoor temperature at the daily maximum temperature was shown in orders of industrial area biotope(36.3℃)＞commercial area biotope(35.5℃)＞high and low floor residential area biotope(34.8℃)＞river biotope(33.9℃)＞forest biotope(30.4℃). Low humidity was created at high temperature region and high humidity was created at low temperature region, there was no special tendency in wind speed but it contributed to creation of outdoor temperature, and surface temperature and globe temperature were measured as same tendency as outdoor temperature. Outdoor temperature at the daily minimum temperature was shown in orders of commercial area biotope(27.5℃)＞industrial area and low floor residential area biotope(26.9℃)＞high floor residential area biotope(26.5℃)＞river biotope(26.6℃)＞forest biotope(26.4℃), humidity was over 80%, and globe temperature was low temperature region with lowest value at forest biotope(26.8℃) and river biotope(26.7℃) that have strong wind speed. As a result of understanding the level of affecting creation of outdoor temperature for each land cover type, impermeable cover area showed positive correlation(correlation coefficient of 0.608) for increase of outdoor temperature, and tree planting area had negative correlation(correlation coefficient of –0.694). It was analyzed surface temperature (correlation coefficient of 0.821) and globe temperature(correlation coefficient of 0.790) had high interrelationship with change in outdoor temperature. Based on this, this study suggested expansion of green and water permeable cover, inflow of air current, and application of a planting method that considered wind corridor as a means to enhance comfort for each biotope type.
