Perception écologique et sociale de la biodiversité des espaces verts urbains publics

The first objective of this thesis was to analyze the underlying processes of the relationship demonstrated in the literature between species diversity in public UGS and psychological restoration of visitors. Our hypothesis was that landscape heterogeneity, an environmental parameter that is related to species diversity within public UGS, is perceivable by visitors and beneficial to their psychological restoration. Following the results, the second objective was to identify planning and management practices of public UGS that promote both biodiversity and visitors’ well-being. We showed that landscape configurational heterogeneity, precisely the mixing of the three strata of vegetation and flower areas, is perceived by visitors and favors their psychological restoration. Landscape heterogeneity is thus an explanatory factor in the relationship demonstrated between species diversity in public UGS and psychological restoration of visitors. We also showed that visitor’s perception of landscape heterogeneity is especially induced by variations in the vegetation height. Moreover, visitor’s gender, childhood environment, and diversity of activities have an influence on their perception of landscape heterogeneity. We then identified planning and management practices of public UGS that enhance the mixing of different heights of the three vegetation strata and flower areas.
