Urban Heat Island has become a serious problem in urban area. Tree is considered as effective measure for mitigating urban heat. The purpose of this study is reviewing urban heat island mitigation effect of tree, focusing on evaluation indices related to temperature reduction. We selected 49 previous studies and classified studies considering type of site and variables related to mitigate urban heat. Studies were classified as tree, vegetation, green roof/wall and green area. Variables of each group were categorized as space, function, individual and environment variables. Each study site showed different mitigation effects and considered different variables. Therefore, plans or designs for green area in urban area should consider differences among sites and use integrated evaluation indices including humidity and wind speed for mitigating urban heat.
