Abstract: In the context of rapid global urbanization, green infrastructure (GI) has attracted attention in urban planning and construction due to its good ecological and environmental benefits. In the present paper, Wuyi County, Jinhua City, Zhejiang Province was selected as the research area, and ArcGIS, GuidosToolBox, Conefor 2.6 and other softwares were applied to analyze the morphological spatial pattern of the land use type of Wuyi County in 1990, 2005 and 2018. The three scenarios of urban development priority, ecological protection priority and natural development were set up, and the CA-Markov model was used to predict the future green infrastructure spatial pattern under the three scenarios. The results showed that the ratio of the area of green infrastructure in Wuyi County to the total area of Wuyi County in 1990—2018 decreased. The area of important core areas and island-like plaques was decreasing, while the area of bridges, pores and branch lines was increasing, and the problem of landscape fragmentation was aggravated. In the scenario simulation in 2030, the GI area of Wuyi County under natural development and urban development priority scenarios would decrease by 171.79 km2 and 225.73 km2, respectively, and the core area would decrease by 84.81 km2 and 126.76 km2, respectively. Under the ecological protection priority scenario, the GI area in Wuyi County would increase by 25.52 km2, and the core area would increase by 69.60 km2. The results showed that if people pursue blindly of rough economic development and neglect ecological protection, the landscape fragmentation in Wuyi County would be further aggravated. Based on this, priority should be given to ecological protection, and tourism development should be moderately regulated in the central and southern regions, to achieve sustainable development in accordance with economic growth and environment.
