Abstract

Creation and administration of green space are emphasized to solve the environmental problem and the management of green space in urban area. Urban area with high development pressure faces green space fragmentation, so the planned approach is needed to improve the continuity of green space. However, the current institutional green axis, used to enhance continuity of urban space is merely an abstract concept under the master plan so that is not a consistent framework for urban green continuity providing no detailed information such as position and path. Therefore, in order to consistently manage green space in continuous point of view, it is insufficient not being connected to each individual green space development projects. This study proposes a method for finding the connection path to enhance urban green space continuity. This proposed method consists of two phases. First phase is finding nodes to connect current green space and second is to calculate the least cost path. We calculate connection cost using NDMI (Normalized Difference Moisture Index), impervious ratio and official land cost, applying to Suwon city and potential greening site that was planned in official master plan. According to the results, we confirm a possibility of finding a cost-effective connection path with detailed spatial information instead of unrealistic abstract concepts and discuss worth applying to a legally plan and policy.

도시의 환경문제 해결과 관리방안으로 자연기반해법(Nature based Solution, NbS)이 대두되면서 도시지역의 녹지 확보 및 관리가 강조되고 있다. 개발 압력이 높은 도시지역은 녹지의 파편화 및 단절로 도시녹지의 연속성 확보를 위한 계획적 접근이 필요하다. 그러나 현행 제도에서 녹지축은 구체적인 녹지와 연결이 필요한 경로의 위치를 제공하지 못하고, 개별 녹지조성사업과 연계되지 못해 연속성 관점에서 일관된 녹지관리 체계로 활용성이 낮다. 따라서 본 연구는 NDMI (Normalized Difference Moisture Index), 불투수율, 녹지조성비용의 정보를 기반으로 연결경로를 도출할 수 있는 방안을 구상하고 수원시에 시범 적용하여 확인하였다. 본 연구에서 제안하는 방법을 통해 기존의 녹지축보다 비용효율성이 높은 구체적인 연결경로의 도출 가능성을 확인하였으며, 계획적 활용 방안에 대해서 논의하였다.
