The present study examines the factors affecting user satisfaction with urban parks. Since urban parks are considered public spaces and one of the basic rights of citizens, it is essential to pay attention to the opinions and demands of citizens to provide better designs for them. The present study aims to study the components enhancing user satisfaction with urban parks and the relationships between them. For this purpose, first, the factors affecting the quality of these spaces and user satisfaction are extracted through library studies. Next, the users of urban parks are surveyed using a researcher-made Likert-scale questionnaire to know how these factors influence user satisfaction. The present study is descriptive-survey research. The statistical population includes the users of parks in Babol City, among which the samples are selected at different hours and days. The present study is based on the issue that user-centered designs can improve user satisfaction. The results indicate that six factors influence user satisfaction, including structure, aesthetics, meaning, security, behavioral patterns, and sociability, and the security and meaning factors are the most and least important factors from the users' point of view, respectively. The high importance of the security component from the users' perspective indicates that the presence of factors such as adequate lighting, the presence of security guards, access control, support of activities, safety of park equipment and facilities, management and maintenance, and surveillance have the greatest impact on the formation of citizens' mental image of the park. There is a significant positive correlation between some of the six components, and the greatest one is observed between the two components of structure and aesthetics with r=0.417. Structure, security, meaning, and sociability factors affect three factors, and aesthetics and behavioral patterns affect two factors.
