도시생태현황지도를 활용한 열취약성 평가 연구: 수원시를 사례로

Abstract

Biotope map is a high-resolution ecological information map that reflects environmental and ecological characteristics and values, and can be used as basic data for sustainable urban management. Its utilization for establishment of urban planning is encouraged nationally, but such action has been rarely implemented. In this study, vulnerability assessment in urban thermal environments of Suwon was conducted based on a biotope map. For the vulnerability assessment, 17 indicators for exposure-sensitivity-adaptability were constructed and utilized based on existing studies related to thermal environments such as heat waves and urban heat islands. As a result of the analysis, the regions belonging to the urban biotope showed a higher overall vulnerability than the green biotope regions. Among urban biotope, higher vulnerability was found in manufacturing, residential and commercial areas with high floor-area ratio and impermeable area ratio. In the unit of administrative districts, Paldal-gu, which has the highest ratio of residential and commercial regions, showed the highest overall vulnerability. Thermal vulnerability clearly depended on the distribution of biotope type, even within the same administrative district. In conclusion, an efficient policy and budgeting regarding the thermal environment of urban city should be implemented in consideration of its biotope type and inner driving factor. This study has a meaning in that it could support the establishment of practical and efficient urban and environmental planning to improve thermal environments based on high-resolution biotope map.
