Daegu City has the most number of heat waves every year in the last 10 years among 7 metropolitan cities in Korea. As the slang, such as ‘Daefrica(Daegu + Africa)’ shown, Daegu City is recognized as a high temperature region in the summer. The purpose of this study is to understand the perception of urban green space as a mediator for heat wave mitigation for Daegu citizens. First, about 93.3% of the respondents perceived what the heat was. The most frequent cause of the increase in the number of heat waves was the increase in energy use (34.9%), ‘indiscriminate development’ (24.9%), ‘automobile and traffic increase’ (17.9%), ‘greenery reduction’ (12.6% ) were the most common cause. Second, 87.1% of respondents had positive perception about the mitigation effect on the effect of urban green space as a medium to mitigate the heat. In addition, 26.7% of respondents answered that they are very effective in mitigating the effect of the heat of urban greenery, and 95.1% of them responded more than ‘normal’. Third, as a result of examining the priorities of short and long-term heat-related policies, the short term was the highest (37.5%) in responding to ‘electricity tariff realization’ because of the high dependence on air conditioners. In contrast to the short-term perspective, the long-term policy for mitigating the heat wave was overwhelmingly supported by ‘expansion of urban green areas’ (50.7%). This is a result of confirming Daegu citizens’ consciousness which is highly evaluating the effect of urban green space as a medium for mitigating the heat. Fourth, the importance and performance of ‘urban green space type’ for mitigation of the heat wave were examined. The type of urban green space belonging to the phenomena maintenance area (quadrant Ⅰ), which both had high importance and performance, was classified as ‘neighborhood park’. In addition, it was surveyed as ‘Ssamji(mini) Park’ as the type of urban greenery in the concentrated improvement area (quadrant Ⅱ) where the importance is high but the performance is low. We believe that the value of urban green areas for mitigating the heat waves has been fully recognized through the recognition of Daegu citizens. We hope that the results of this study will be used as basic data for future Daegu city heat and urban greening policy.
