Comparison of two different approaches for assessing the psychological and social dimensions of green spaces

摘要

Urban forests, trees and other green spaces are thought to contribute significantly to certain psychophysical and social needs of urban dwellers. Recent studies on citizens' perceptions and behaviour toward urban green areas have shown the complexityand the multidimensional character of the man-nature relationship in the city; inhabitants' use of green spaces appears to be motivated by the need for psychological health with relevant social implications. In this paper, we describe two empirical studies that have been independently conducted and recently published by Italian urban foresters and environmental psychologists. By comparing the two studies in terms of approach, materials, methods and results, we seek to find out if urban foresters and environmental psychologists in Italy approach and interpret the psychological and social (P&S) dimensions of urban green spaces differently. Results show that urban foresters have applied substantially different approaches and research methods than environmental psychologists. This can be explained from their different backgrounds and perspectives. We conclude by discussing some basic hints and implications for enhancing the P&S benefits of urban forests through collaborative projects and scientific co-operation between urban foresters and environmental psychologists.
