Abstract

Green infrastructure(GI) is considered a key strategy in establishing sustainable communities. However, research on GI from the perspective of urban system dynamics and resilience lacks depth, as does its integration with physical design. This research addresses two primary causes. First, there is a gap in methods between existing GI planning, which considers static variables, and urban modeling research, which addresses dynamic variables. Second, there is a gap in information between landscape design and urban modeling research. To address these issues, this study proposes an integrated modeling approach in consideration of design decision-making. By combining the LEAM model and MCDA model, this study evaluates the relationship between GI services and socioeconomic growth, while spatially forecasting the geographies of GI demand in 2050. The resulting information reveals a potential degradation in ecosystem services over the region due to Chicago's sub-urbanization. This indicates that there would be a spatial shift in GI demand, emphasizing the need for comprehensive, dynamic GI strategies. This study further discusses the applications of evidence-based design in a studio environment. This study aims to contribute to the GeoDesign literature in terms of the creation of a more resilient urban environment by facilitating efficient evidence-based decision-making.

그린인프라는 지속가능한 커뮤니티를 조성하는 데에 주요한 전략으로 고려되고 있다. 하지만 도시 레질리언스와 시스템의 역동성이라는 관점에서 그린인프라에 관한 연구는 아직 부족하며 이를 어떻게 물리적인 적용과 융합하는가에 관한 연구 역시 미미하다. 본 연구는 두 가지의 원인에 주목한다. 첫째는 정적변수를 고려하는 기존의 그린인프라 계획과 동적변수를 고려하는 도시모델링 연구 사이의 간극이며, 둘째는 도시모델링 연구와 조경설계 간의 정보 및 방법의 차이이다. 본 연구는 도시성장에 따른 그린인프라의 수요의 분포를 전망하며 설계의사결정을 지원하는 융합모델링을 제안한다. LEAM모델과 MCDA모델을 융합하여 그린인프라의 서비스와 사회경제적 도시변화의 관계성을 평가하고, 2050년의 그린인프라의 수요를 공간적으로 전망한다. 모델의 결과는 시카고 외곽에서의 도시화가 진행될수록 생태시스템 서비스의 질적 저하가 일어날 가능성이 있음을 말한다. 이는 경제성장에 의해 그린인프라에 대한 수요가 지리적으로 변화할 수 있음을 나타내며, 그린인프라 전략이 현재와 미래를 유동적이자 포괄적으로 고려해야 함을 제안한다. 나아가 본 연구는 스튜디오 환경에서의 생산된 정보를 학생들과 공유하여 근거기반 설계의 적용과 가능성에 관해 논의한다. 지오디자인의 관점에서 그린인프라 설계 및 계획과 도시시스템 연구의 융합을 통해 효율적인 설계의사결정을 지원함으로써 보다 탄력적인 도시환경을 조성하는데 기여하고자 한다.
