Despite the various environmental and ecological benefits of green spaces, the diminution and disconnection of green axes are becoming significant challenges due to rapid urbanization. To enhance the connectivity of urban greeneries, a green infrastructure plan presenting comprehensive green-axis measures allowing for regional characteristics is in need. This study examines the connectiveness of existing green spaces and derives new green axes for two types of cities in Incheon, South Korea: Yeonsu-gu (a new town) and Namdong-gu (an old city center). By conducting connectivity analysis through utilizing GIS and Conefor, three types of greenery are categorized and visualized: significant core, complementary core, and stepping stone greenery. The results show that Yeonsu-gu contained 13 significant cores (IIC: 0.74-35.44), 19 complementary cores (PC: 0.06-4.24), and 12 nodes, while Namdong-gu had six significant cores (IIC: 0.14-18.99), 15 complementary cores (PC: 0.06-3.25), and 13 nodes. Based on the results, two additional green axes are proposed for Yeonsu and Namdong-gu with policy recommendations to better link isolated green patches. The results of this study provide insights to local planners and decision-makers about how they can effectively maintain and improve the overall green infrastructure network in the long-term.
