Abstract: With the increasing frequency of extreme disasters, effectively utilizing park green spaces in both daily life and disaster scenarios has emerged as a new challenge, particularly in county-level cities. In this context, the core planning area of Anxi County in Quanzhou was selected as the study site. By adjusting the layout and scale of park green spaces, this research investigates how such modifications influence the quality of the urban wind environment and green space accessibility in county-level cities. The results show the following: (1) Under the vegetation ratio of trees–shrubs–herbaceous plants, the ventilation performance of the urban wind environment improved at a daily wind speed of 5 m/s. The wind speed increased from the current low base speed (0–1 m/s) to a moderate speed (2–5 m/s), significantly enhancing the comfort of the population. (2) Under the vegetation ratio of trees–shrubs–herbaceous plants, the overall disaster-prevention performance of the county improved. During typhoon wind speeds (50 m/s), the wind speed gradually decreased from partially higher speeds (40–50 m/s) to lower speeds (10–20 m/s), resulting in a significant improvement in the wind environment. (3) After optimizing the layout of park green spaces, accessibility was greatly enhanced, better meeting the needs of the population in the developed area.
