From urban greenspace to health behaviors: An ecosystem services-mediated perspective

Urban greenspace can provide important health benefits for urban residents, but knowledge about the potential mechanisms remains unclear, and it is challenging in promoting health behaviors through design and management practices. This study proposed a hypothetical model that assumed ecosystem services as mediating factors between urban greenspace and health behaviors. An urban park in Beijing was selected as a case area to test the hypothesis and identify the ecosystem services-mediated pathways. Results based on spatial explicit mapping and multivariate statistical analysis confirmed the hypothesis and showed that urban greenspaces contribute to health behaviors in varying degrees through the delivery of health behaviors-related ecosystem services. The promotion effect was mainly mediated by cultural services, which is much more obvious than regulating services. We identified the importance of different properties of inner urban greenspace in promoting health behaviors through ecosystem services-mediated pathways. Green elements, especially tree canopy shaded ground, were found to contribute the most to health behaviors in the pathways, and slightly higher than facilities and grey elements. To promote health benefits, the design and arrangement of facilities and grey elements in urban greenspace is suggested to be cooperated with green elements for enhancing multiple ecosystem services. The findings will enhance the understanding of potential theoretical pathways from urban greenspace to health benefits, and support health promotion-oriented design and management practices.
