Biodiversity Perception,Preference and Recovery Benefits in Different Green Spaces
The relationship between biodiversity and human health and well-being is complex,and it is imperative to understand residents'perceptions,preferences,and recovery from biodiversity.Using different experimental designs,four common green space types in the city were selected:streets,squares,lawns and forests.Panoramic images of cross-compositions of species richness and color diversity at different high and low levels in the four green space types simulated by Mars were used as visual stimulus material.A questionnaire survey was conducted to find out information about perceptions,preferences,and recovery of the four green space types at different levels of biodiversity from 695 respondents.The analytical results have indicated the following findings.1)The species richness of the forest was positively correlated with perception,preference and recovery,and the respondents preferred forests with a single green color.The richness of groundcover color in lawns was an essential element for identifying biodiversity;high species-rich lawns with a single green color were not preferred by respondents,while increasing groundcover color improved the experience of lawn landscapes.Respondents preferred streets and squares with vegetation to those without.2)Respondents'perception,preference and recovery were positively correlated,while preference and psychological recovery for biodiversity depended more on their perception than actual species richness.3)Different forms of experimental design made a significant difference in the study's results,and a combination of the two can better avoid legacy and demand effects than a separate between-or within-subjects design.The findings in this paper aim to clarify the factors influencing urban residents'perception,preferences,and restoration of biodiversity,in order to provide theoretical bases and practical methods for biodiversity-oriented urban green space planning and management in the future.
