In the development model of urbanization, the division and content of urban spaces tend to be functional considerations while neglecting the needs of human emotion and natural ecology. The fragmentation and geometrization of urban green spaces have grown gradually and counteractively to nature. This research sought to understand and analyze whether experts and the public had the same aesthetic cognition of the formal style and the natural ecology in the design of urban green spaces. First, from the literature review, this study defined the four types of landscape ecological aesthetics of urban green spaces using the landscape ecological aesthetic evaluation matrix. It then examined the relationships among place attachment, landscape aesthetics, and preferences for urban green spaces . In addition, this study analyzed how differences in social and economic backgrounds and personal characteristics affected place attachment, landscape aesthetic evaluation, and preference. The results of the study showed that there were no significant differences in the landscape ecological aesthetic evaluation, preference, and place attachment for the different types of green spaces. Respondents' aesthetic evaluation of parks with low ecology and middle aesthetics was higher than that of parks with high ecology and high aesthetics, indicating that there were still differences in cognition between respondents and experts. Place attachment positively affected the aesthetic evaluation and preference of landscape ecology. Individual socioeconomic backgrounds and personal characteristics showed some significant influences on landscape ecological aesthetic evaluation, preference, and place attachment. The results of this study could be used by the public works department and landscape designers when considering how to balance natural ecology and landscape aesthetics in the planning and design of urban spaces.
