| China’s population aging trend gradually intensified,improving the leisure-time physical activity of elderly people has become a hot issue in the realm of public health research.Neighbourhood green space,as the nearest space to the daily leisuretime physical activity,exploring the effect of its spatial characteristics on elderly leisure-time physical activity is of great significance to give full play to the health benefits of neighbourhood green space.Taking open green space of aging neighbourhood in central Harbin as research object,this study parses the elderly leisure-time physical activity(LTPA)and neighbourhood green space characteristics from the perspective of Environmental Behavior.Not only identified the spatial characteristics that correlated with the density of leisure physical activity of elderly people,describeing its influencing mechanism and effect differences,but also put forward the guidelines for optimizing the spatial characteristics of neighbourhood green space from the perspective of healthy aging.Firstly,to clarify the interaction relationship between elderly LTPA and neighbourhood green space,this study introduced theory of social ecology environmental factors and environmental behavior mutual penetration and cognitive psychology cognitive hierarchy,also put forward a research framework of the correlation between neighbourhood green space characteristics and elderly LTPA,which is based on "related factor recognition-single dimension influence mechanism exposition-dimensional difference comparisonn".Secondly,based on previous research results,the first-level indicators of neighbourhood green space characteristics are defined,including spatial distribution,spatial fo rm and spatial facilities,as well as specific quantitative techniques and methods.On the basis of Open Street Map and with the help of spatial syntax Depthmap software,this paper quantifies the spatial distribution of neighbourhood green space at the whole and the part,such as the identifability,travel frequency and compactness.The spatial form of neighbourhood green space at three levels of scale,interface and vision are quantified by Arc GIS spatial analysis tools,Rayman model,Seg NET image analysi s tool.The spatial facilities of neighbourhood green space,includeing leisure physical activity facilities and auxiliary facilities and quantified by field survey and statistics.Thirdly,taking population composition,location characteristics,residenti al type and community texture as control variables,the neighbourhood green space research sample was selected.Several investigators were recruited to use SOPARC to collect the data of individual attributes,activity content,activity intensity and number of the elderly.In the mean time,the corresponding quantitative technology and methods are used to collect the spatial characteristics data of community green space.Finally,with the help of SPSS data analysis platform,an empirical model of the correlation between the spatial characteristics of neighbourhood green space and the density of elderly LTPA is constructed.The spatial characteristic factors of neighbourhood green space affecting the LTPA density are identified by correlation analysis;the influence mechanism,suitable value range and influence difference of various spatial characteristic factors on the LTPA density are elaborated by simple regression analysis and multiple regression analysis;and all kinds of significant correlation spatial characteristics are synthesized.Multidimensional regression analysis was carried out to compare the spatial characteristics of various types of neighbourhood green space with the impact of elderly leisure physical activity density.In the mean time,based on the above empirical analysis results,from the three levels of spatial layout characteristics,spatial morphology characteristics and spatial facilities characteristics,this paper puts forward the guidelines for optimizing neibourhood green space to promote leisure-time physical activities of elderly people from the perspective of healthy aging.The purpose of this study is to explore the correlation between LTPA of elderly people and the spatial characteristics of community green space step by step from surface to interior planning layout to space design.The aim is to optimize the spatial characteristics of community green space scientifically and timely,to implement the "Combination of Green space and LTPA" and improve the planning of community green space system,and to promote the elderly friendly society in China.District construction lays the foundation for guiding and promoting the construction and improvement of neighbourhood green space system from the perspective of elderly LTPA. |
