Classification of Urban Community Jogging Environment based on Multi-source Data:A Case Study based on Jinshan Street in Fuzhou City
Against the background of building sports-friendly cities and residents'pursuit of a healthy life around China,the urban community jogging environment is becoming a research hotspot in the field of landscape architecture and planning.In this context,it is particularly important to summarize and analyze the current characteristics of the urban community jogging environment and conduct in-depth research on the existing problems.The classification and spatial optimization of the jogging environment in urban communities would be helpful to improve the health-promoting livability of communities and enhance the exercise intention of residents.In the present study,a case study based on Jinshan Street in Fuzhou City was performed.The community-oriented urban community jogging environment was evaluated by the combination weighting method from the four perspectives of diversity,safety,accessibility,and comfort.A multi-index and multilayer evaluation of the urban community jogging environment was conducted by combining space syntax,image semantic recognition of machine learning fitting and the expert scoring method based on street view images,field survey data,and questionnaire survey results.The results demonstrated the following.(1)Comfort is the most critical influencing factor in the criterion layer of the community jogging environment evaluation index system,followed by safety,accessibility,and diversity.Among level-2 indexes,the night lighting effect,social security,road width,pavement smoothness,and natural landscape richness were important.(2)The jogging environment varied greatly with location and the geographical environment.Based on the four-criterion layer in the community jogging environment evaluation system,the jogging paths could be divided into four types:vigorous running type,green running type,pleasant running type,and convenient slow running type.(3)The vigorous running type showed a relatively good general environment,with the best comfort and safety.The green running type had relatively good safety and comfort but the accessibility required improvement.The pleasant running type had good environmental comfort and accessibility but safety and diversity were poor.The quality of the convenient slow-running environment was generally poor and required high attention.According to a summary of the characteristics,differences,and problems of different types of community jogging environments,some targeted optimization strategies were proposed in terms of road networks,service facilities,and environmental quality.For the vigorous running type,perfecting the construction of basic services and optimizing the diversity of the jogging space are suggested.For the green running type,appropriately increasing the road network density and connectivity is suggested.For the pleasant running type,the quality of the jogging environment and improvement of public security management are suggested.For the convenient slow jogging type,it is recommended that the concept of"green and convenient"be advocated when improving construction.Thus,the community jogging environment was comprehensively evaluated from the perspective of different demands/needs,which provides new perspectives for the planning of livable community environments and inspiring the creation of sports-friendly cities.
