Associations between greenspace characteristics and population emotion perceptions in three dimensions

Introduction: Mental disorders are considered to be the most significant threat public health. Mitigation effects of urban green spaces have been widely documented. However, conclusions inconsistent because representativeness original data. Method: We measured mental perception using geospatial big data instead field observation or questionnaire Street view were applied calculate space characteristics in three dimensions. Results: The positive percentage around chosen parks increased as buffer diameter decreased. temporal variations perceptions selected exhibited an obvious peak-trough shape. spatial associations between and varied geographically. became less similar At same scale level, played a dominant role distribution perceptions. Discussion: Shrinking deviations increasing mean maximum values will favor improvement This study provides reference for explaining ecological scientific questions spatiotemporal It also insights into mechanisms underlying relationship processes
