Research On Correlation Between Urban Built Environment And Linear Physical Activities

With the development of national fitness program and the improvement of residents' health awareness,people begin to use their leisure time to do health exercise,and national health is regarded as a basic national policy on the nineteen National People's Congress.However,the deterioration of environmental problems and unequal distribution of resources make it difficult for residents to meet the needs of physical activities.Therefore,the research on the relationship between urban built environment and physical activities has become the key point to promote the social health level,especially the built environment of the residents physical activities is the key issue of the study.Access to sports enthusiasts in this study "Gudong" data platform for the sports activities and data platform in the city planning bureau built environment data as the data source,using Arc GIS and SPSS for data processing and analysis,on the basis of the existing theoretical research,analysis of city built environment effect on the impact of walking,running and riding three linear physical activities.Quantitative research is the main research method in this study.Based on the built environment and physical activity related to the domestic and foreign research review,research of Harbin built environment and physical activities in general linear,determine the built environment index system in the study of the city,which is divided into environmental factors and spatial index level to two.The correlation between the two is studied at the macro level and the meso level respectively.Analysis of factors of macro level mainly study the built environment influence on linear sports activities,choice of city streets as the analysis unit,the mixed land degree,population density,road density,bus station density,park green density,POI density and NDVI as the independent variables and the dependent variable linear physical activity density and diversity,and correlation analysis regression analysis of variables,determine the built environment elements have an impact on linear sports activities.The results show that road density,park green density,bus station density and population density and NDVI have an influence on the overall distribution of linear sports activities.Specifically,(1)road density,park green density,bus station density,NDVI and activity density were positively correlated;(2)road density,park green density and population density,NDVI and activity diversity were positively correlated.Analysis of space built environment on linear sports activities affect the medium level,with sports activities around the route buffer area as the research unit,for walking,running and cycling of three types of activities of the overall distribution,route environment indicators and elements of space to compare,built environment preferences and activity mode summary of different types of sports activities,and then put forward the running Avenue and suitable for riding the city corridor to promote residents sports city outdoor space optimization suggestion community,construction of suitable for walking activities.Study on the correlation between city built environment and linear sports activities,and provides a theoretical basis for the transformation of city outdoor space,also provide technical support for other city,provide for the field of public health,physical education,landscape environment,urban and rural planning theory and practice significance.
