Urban Parks-A Catalyst for Activities! The Effect of the Perceived Characteristics of the Urban Park Environment on Children's Physical Activity Levels

The potential of urban parks to enhance social welfare and deliver health benefits has been recognized. However, it is still unclear which landscape characteristics in urban green spaces best improve the physical activity levels of users. Little is known about the relationship between the microenvironment of urban green spaces and the physical activity of children, particularly in the context of high levels of childhood obesity. Using the self-report method, we extracted the perceived environmental characteristics of the landscape and combined this with behavior observation to obtain the level of children's physical activity in green spaces and to explore the influence of the characteristics of green spaces on these activities. Our results show that the highest levels of activity were found in the semiopen spaces of urban parks, which mainly consist of dense vegetation and a diverse range of recreation facilities. Play facilities were most closely related to the level of intensity of children's activities, and perceived safety was the primary social perception factor affecting their activities. In addition, perceptions of the social environment were found to play a significant intermediary role in the impact of green space on children's physical activity. The study results are intended to promote green space planning and design updates, improve the public health level of children, and provide a basis for the construction of child-friendly cities.
