| Under the background of the strong support of national policies for the development of national sports activities and the transformation of urban space environment construction from incremental development to stock development,large-scale linear sports activities have become an important opportunity to promote the fine development of cities,leverage local economy and promote the construction of urban public green space.As the carrier of large-scale linear sports activities,urban street is not only an important place for residents’ daily life,but also plays a supporting role for people in the linear sports activities.Creating a dynamic,adaptable,beautiful and reasonable street landscape is an important channel to achieve urban connotative upgrading and meet the needs of residents for a better life.Nowadays,there are still some problems such as uneven distribution and waste of space resources,which can not meet the needs of people’s spontaneous decentralized outdoor sports,nor can they cope with the holding of large-scale linear sports activities,which not only weakens the enthusiasm of urban residents for sports,but also ignores the daily relationship between landscape space and residents’ sports.With the rapid development of Internet technology,new types of data are constantly emerging,which has become an indispensable and important platform for streetscape research.Based on the above background,this paper introduces the theory of landscape resilience,and further explores the application of resilience in the evaluation of streetscape from the perspective of responding to online and offline large-scale linear sports activities.It can not only enhance the stability,coordination and initiative of urban streetscape,promote urban development and construction,but also actively respond to the urgent needs of people for public activity space,as follows:(1)Summarize the theoretical basis of this study.Combing large-scale linear sports activities,streetscape,domestic and foreign toughness,space toughness and landscape toughness of the relevant theories and practical cases,summarized the previous research progress in the evaluation of streetscape and toughness.By exploring the feasibility of toughness theory applied to the streetscape space,this paper analyzes the inadaptability between the development of online and offline large-scale linear sports activities and the current streetscape,and provides reference for this study.(2)Response to online and offline large-scale linear sports activities to build streetscape resilience evaluation system.Usually,offline linear sports activities are more concentrated,while online activities are mainly spontaneous decentralized or daily sports.Based on their pressure on the streetscape,combined with literature research,Expert consultation and AHP(Analytic Hierarchy Process)-PSR(Pressure-State-Response)comprehensive method are used to scientifically preset,reasonably screen and precisely quantify the toughness elements of streetscape,and to build a fully reliable evaluation system of streetscape toughness.With the rise of big data and artificial intelligence technology,this paper studies the resilience elements of streetscape with the help of Baidu thermodynamic map,POI(interest),street view pictures and ArcGIS10.5 spatial analysis tools,and determines three criteria layers of pressure,state and response.Human and natural factors,street safety,street comfort,street functionality,predictive ability and adaptability,The hierarchical structure model of streetscape resilience evaluation in response to large-scale linear sports activities was constructed,and the weight value of each resilience evaluation index was finally determined,and its meaning and quantitative method were described in detail.(3)An empirical study on the resilience of urban streetscape in Fuzhou was carried out.Establish the basic database of Fuzhou main city streets based on Baidu thermal,POI and street view image data,and conduct quantitative and qualitative analysis of the streetscape in the study area based on the established evaluation system of streetscape toughness.Using SPSS software,field exploration,questionnaire survey,GIS spatial analysis tools to evaluate the resilience of urban street landscape in response to online and offline large-scale linear sports activities in Fuzhou and get the toughness score.(4)Finally,the optimization and promotion strategy of streetscape toughness is put forward.From the response of online and offline large-scale linear sports activities as the breakthrough point,in order to solve the practical problems faced by the streetscape.From the three aspects of pressure source repair and resistance,state adaptability optimization,and response efficiency enhancement,this paper puts forward the resilience enhancement strategy of streetscape in line with the response of online and offline large-scale linear sports activities:Absorb and cope with the interference of natural factors;Enhance the continuity of street landscape culture;Flexible according to the gathering state of the crowd;Establish a safe and stable resilience space;Strengthen the stability of functional facilities;Improve the comfort of street landscape;Expanding various ways of publicity and participation;To guide the enthusiasm of public participation.The above three levels of eight strategies can be actively applied to different types of streetscape,in order to enhance the resilience level of streetscape space.Finally,in response to online and offline two types of large-scale linear sports activities,taking the streets of Fuzhou main urban area as an example,this paper makes the optimization strategy of applicability,initiative and toughness of streetscape.This paper is to respond to the online and offline large-scale linear sports activities of the streetscape toughness to do exploratory research,will optimize and enhance the streetscape toughness as the current key development of the new normal,try to establish a combination of qualitative and quantitative,scientific and reasonable evaluation system of streetscape toughness,in order to provide a reference for the optimization of streetscape. |
