The Optimization On Built Environment Of The Residential Communities Promoting Active Living

Due to a rapid industrial expansion and urbanization during the last few decades in China,the increasingly occurrence of haze or smog episodes have been report,causing the government and public on the completion of environmental and health issues of widespread concern.The World Health Organization defines health as a state of complete physical,mental and social well-being and not merely the absence of disease or infirmity.A large number of studies have shown that through the optimization of the built environment can encourage residents to participate in physical activity and daily exercise,thereby promoting physical and mental health.The aim of this study was to explore the relationship between human behavior and built environment to support an active living style.The purpose of the study was(1)to explore the regularity of the environment for the promotion of active living,(2)to consider the impact of environmental preferences on the selection of physical activity,(3)to provide basic data for planning and design practice case.In this paper,the literature research method and comparative study were used to analyze cases of active living implemented in western countries.Using the system science analysis,the questionnaire survey method and the quantitative analysis as the empirical research method,this paper analyzed the relationship between the environment,transport-related walking and the emotional aspects.The literature review found that density,land use,street connection,sidewalks and social environment had a significant impact on physical activity.The empirical data was analyzed through the test of reliability and validity of the questionnaire,exploratory factor analysis,correlation analysis.The questions were reorganized and finally established generalized linear models.The results showed that the demographic characteristics and perceived built environment had no significant effect on transport-related walking.Aesthetics and emotional factors were associated with behavior preference.Personal preference had an impact on walking duration and destination.Neighborhood attachment was significantly influenced by green space,aesthetics,security,social activities and social interaction.Relying on the social ecology model,this paper put forward three aspects of optimization strategy,policy guidance,public participation and design guidance.In addition,this paper proposed environmental optimization design methods,including space environment,place environment and social environment.From the theory to the empirical,China's current research on the promotion of active living are in the ascendant.The implementation of the strategy still need to transfer from theory to practice.
