Influence Of External Environment On Running Behavior Of Citizens In Winter City

With the rapid development of urbanization and the accelerating pace of life,obesity,cardiovascular disease and mental health problems have become the main health problems faced by urban residents.How to effectively improve the physical quality of the citizens and promote the citizens to carry out outdoor sports has become an urgent problem to be solved.Compared with the guidance issued by the government and the publicity and guidance of the media,playing the attraction role of the built-up environment of the city to outdoor sports can enhance the citizens’ willingness to outdoor sports,and then improve the physical quality of urban residents and the construction of a healthy city.Previous studies have proved the impact of urban external environment on outdoor sports behavior,but different climate conditions and different urban characteristics lead to certain regional research.For Winter Cities with huge temperature difference in winter and summer,the existing research conclusions may not be applicable.In addition,there are some problems in the current research,such as the limitation of data sources,the locality of research scale and the one sidedness of index selection.As one of the representatives of outdoor sports,outside running has become one of the most popular exercise methods for contemporary citizens because of its flexibility of location and time.In order to explore the external environmental factors that affect the outside running of citizens in Winter Cities and improve the suitability of outdoor sports space in Winter Cities,this paper takes Harbin,Changchun and Shenyang as examples,systematically combs the theory of environment behavior relationship and related research,based on the perspective of micro individual behavior,starting from exploring the factors that affect outside running behavior,Based on multi-source data,this paper systematically constructs the analysis framework of the relationship between weather,built environment and outside running behavior,explores the influencing factors through logit regression model and Pearson correlation analysis,and analyzes the influence degree of relevant factors by using least square regression model and spatial regression error model,so as to integrate the capture of spatial heterogeneity into the analysis,So as to more truly analyze the internal micro mechanism between urban external environment and outside running behavior.The results show that the urban external environment significantly affects the outside running behavior of urban residents in Winter Cities,and the influencing factors and degrees are different between the suitable season and the cold season.The specific conclusions are as follows(1)Temperature,humidity,cloud cover,wind and air pressure are the main factors that affect the outside running behavior of citizens in cold cities.During the suitable season,temperature,wind and cloud cover have a positive effect on the frequency and duration of outside running,while air pressure has a negative effect on it;During the cold season,temperature has a positive effect on outside running behavior,while air pressure,cloud cover,humidity and wind have a negative effect on outside running behavior.Harbin,Changchun and Shenyang are affected by the difference of land and sea location.Harbin citizens are more sensitive to the weather change,and the weather effect is the most significant;(2)Built environment influences outside running behavior mainly through road,natural environment,building environment and traffic.Among them,road grade,street tranquility,green vision rate,near water,street openness,near park square,public transport service level and obstacles of vehicles to sports are the main factors that affect the characteristics of outside running behavior.Due to the influence of urban planning and urban form,some factors(road grade,green visibility,near park,etc.)have great differences among the three cities;(3)Because of the hedonic nature of outside running,people do not always choose the shortest route between the starting point and the destination.Among them,street tranquility,winter green vision rate,near water,near the park square play a major impact on the choice of outside running path.
