Following the September $12^{th}$, 2016 earthquake in Gyeongju-city, the observation can be made that South Korea is not a non-earthquake country. Because of its particular characteristics, urban green spaces are good sites for protection during an earthquake but studies regarding the suitability of park green spaces as a form of earthquake shelter are few, making it difficult to highlight the function of park green spaces as emergency shelters. The purpose of this study is to identify indicators for suitability impact factors of comprehensive parks as emergency earthquake shelter zones. Using the Delphi method, three rounds of survey were implemented. According to the analysis results of Average value, CVR, Consultation and Convergence, ten candidate indicators were removed in the candidate group. Twenty-seven suitability impact factors of comprehensive parks were retained, including 8 indicators in the field of safety, 6 indicators in the field of accessibility, and 13 indicators in the field of service effectiveness.

Construction of urban emergency shelters based on disaster-prevention green space is an important part of an urban disaster response plan. The accessibility of disaster-prevention green space is directly related to the disaster prevention service effect of green space. Taking the Jung-gu and Nam-gu districts of Ulsan city as research targets, the accessibility of three green spaces was analyzed by a network analysis method based on information regarding the distribution of population and green space and the urban road network. Two indicators for evaluating the service effect of green spaces were service population rate and service area rate. The results showed that the accessibility of the emergency refuge parks (5min) and central refuge parks was relatively good but the service area rate and service population rate of the emergency refuge parks (3min) and temporary refuge parks was less than 60%. In view of the overall situation, the service effect of disaster-prevention green space is at this point only general in Ulsan and there is great room for improvement.
