Research On The Influence Of Types And Features Of Blue-green Space On Pressure Recovery

The health performance of restorative environment has been confirmed by a large number of empirical studies.Most of the correlation analysis between restorative environment and health benefit evaluation compares the differences between natural environment and artificial environment,and gradually focuses on the fine characteristics of environment and the impact of elements on human health.However,at present,the research on the environmental restorative benefits mainly focuses on green space,which lacks the overall consideration of the blue-green space including waterscape space,and does not fully compare the differences in the restorative effects of different space types and characteristics.Therefore,this study uses pictures to simulate the environment,excavates the types and spatial characteristics of the blue-green space with high restorative potential,and through the environment The effect of blue-green space on pressure recovery was studied by simulation experiment.Based on the theory of restorative environment,this study firstly summarizes the types and characteristics of restorative environment space involved in the previous empirical research through literature,and then selects the real blue-green space pictures with good restorative benefits and establishes the virtual space scene pictures with different spatial characteristics,and then combines subjective perception and objective physiological indicators through environmental simulation experiments To evaluate the restorative effect of blue-green space,and to analyze the difference of psychological and physiological effects of typical blue-green space.Considering the four main factors that affect the spatial characteristics of blue-green,including green view rate,blue view rate,openness and complexity,this paper explores the urban waterfront spatial characteristics with good restorative effect,and analyzes the relationship between environmental preference and perceived restorability.Finally,based on the mental health of urban blue-green space evidencebased design recommendations.The results show that the recovery efficiency of different types of restorative space is different: the recoverability of mountain view,farmland and waterscape space is significantly higher than that of other types of space,and the preference of people for waterscape space is greater than that of green space;from the perspective of blue-green space type,the recoverability of sea view and inland natural waterscape is significantly higher than that of urban natural waterscape;from the perspective of spatial characteristics,the recoverability of blue-green space is lower The results showed that environmental preference had significant correlation with perceptual recovery evaluation.In this study,the blue-green space types and spatial characteristics with good recoverability obtained from the experiment can be used as the basis of health landscape design,as well as the construction of restorative environment picture library,which can be used as environmental stimulus materials in the field of rehabilitation medicine and provide theoretical basis for the future environmental intervention methods to promote mental health recovery.
