Study On Landscape Renewal Of Slow Streets And Lanes In Ancient City Historic And Cultural Area Of Changsha

Over-development of the city has caused serious damage to the ancient city landscape,and the old streets and alleys are lacking in landscape vitality.In the context of building a strong cultural country and vigorously promoting double carbon goals,there is a good coupling relationship between old city streets and slow walking.By renewing the landscape of old city streets and alleys,it can awaken the vitality of old streets and arouse people’s interest in slow walking,which is conducive to the promotion of slow walking,slow touring,slow eating,slow shopping and slow appreciation of life style,thus achieving the purpose of ancient city revival and achieve dual carbon goals win-win.This paper takes the historical and cultural landscape of the ancient city of Changsha(hereinafter referred to as the "ancient city landscape")and its streets and alleys as the research object from the perspective of slow walking,and through theoretical research,case study,sampling survey,combined with PSPL research method and SD semantic difference method,three levels of macro,meso and micro field research and The main research process and results are as follows.(1)This paper firstly investigates the literature,theories and cases,as well as the current situation of the slow-moving street landscape in the old city,based on which the development rules of the old city and slow-moving streets are explored,the significance of slow-moving for the development of the old city is clarified,the characteristics,problems and the necessity of renewal of the slow-moving street landscape in the old city,and West Wenmiao Ping is selected as the empirical area.(2)Secondly,according to the "Public Space-Public Life" research method(hereinafter referred to as the "PSPL Research Method"),the PSPL slow street landscape evaluation system that conforms to the characteristics of the ancient city and slow street should be constructed by combining qualitative and quantitative methods.The landscape of slow streets and lanes in Xiwenmiaoping was investigated and evaluated,and SD Method of Semantic difference was used to assign the evaluation results.The specific results are as follows:PS street public space landscape total average value 3.22,of which the overall street space D/H ratio is between 0.5-1,which is a compact space;street space interface total average value 3.66,which is an average interface;street space quality average value 3.1,of which the highest score is 4.33 for historicity and the lowest score is 2.66 for comfort and pleasure,indicating that the location is rich in historical resources,but However,there is a lack of landscape experience;the total average value of street and alley landscape elements is 3,which is a bland landscape.PL street public life landscape total average value 3.19.The total average value of slow walking activity is 3 points,including 3 points for walking and 2.83 points for cycling,of which the safety of cycling is only 1 point,which needs to be focused on transformation.The total mean value of stopping activity behavior is 3.75,which is average and above,indicating that the lot provides more opportunities for pedestrians to participate in activities.(3)To synthesize the above research,the PSPL evaluation results are used as a guide to propose spatially guided planning and landscape-designed renewal strategies for the streets and alleys,and to carry out renewal practices in terms of master planning,slow walking route design,fa(?)ade renovation,spatial utilization,plant design and historical preservation,providing theoretical and practical guidance for the development of the ancient city and the renewal of the street landscape.
