Coastal cities face increasing natural disaster risks. Developing a green infrastructure network can reduce coastal vulnerability by connecting green spaces. Only a few researchers have examined practical guidelines for a green infrastructure network in coastal cities. Therefore, the purpose of this study is to build a green infrastructure network by integrating potential evacuation routes and green spaces in a coastal city. The Haeundae District in South Korea was chosen as the study site. We constructed a green infrastructure network using space syntax and GIS network analysis. The results of this study showed that first, we created an integrated green infrastructure network by building evacuation route networks and urban ecological networks. Second, we evaluated the evacuation function and flood risk. Finally, we proposed green infrastructure network planning for coastal disasters, including hub and corridor design. This study can contribute to establishing strategies to reduce vulnerability in coastal cities.
沿海城市面临着日益增加的自然灾害风险。通过连接绿地来发展绿色基础设施网络可以降低沿海地区的脆弱性。只有少数研究人员探讨过沿海城市绿色基础设施网络的实用指南。因此，本研究的目的是通过整合沿海城市的潜在疏散路线和绿地来构建绿色基础设施网络。韩国的海云台地区被选为研究地点。我们运用空间句法和地理信息系统网络分析构建了一个绿色基础设施网络。本研究结果表明，首先，我们通过构建疏散路线网络和城市生态网络创建了一个综合的绿色基础设施网络。其次，我们评估了疏散功能和洪水风险。最后，我们提出了针对沿海灾害的绿色基础设施网络规划，包括枢纽和廊道设计。本研究有助于制定降低沿海城市脆弱性的策略。
