Abstract

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.

방재공원을 주제로 하는 도시 내 응급대피 장소의 건설은 국내외 도시재해 대책에 있어 중요한 요소이다. 특히 방재 역할을 하는 도시 내 공원녹지의 접근성은 방재 서비스 효과와도 직결된다. 본 연구는 울산시 중구와 남구를 대상으로 도로망과 인구분포 및 공원녹지 지리정보와 ArcGIS 네트워크 분석 기법을 이용하여 3가지 유형의 방재공원 접근성을 분석하고, 서비스 면적율과 서비스 인구율 등 2개 지표를 통하여 울산시 방재공원녹지의 서비스 효과를 평가하였다. 평가 결과, 긴급대피 공원녹지(5분)와 중심대피 공원녹지의 접근성은 양호하지만, 긴급대피 공원녹지(3분)와 임시대피공원녹지의 서비스구역 면적과 인구는 전체의 60% 이하로 불량한 것으로 나타났다. 울산시 방재공원녹지의 전체적인 서비스 효과는 이상적이 못하기 때문에 방재공원녹지 체계에 많은 개선이 필요하다고 판단된다.
