Research On Urban Park Renovation Design Based On Quantitative Analysis

Since the 18th National Congress of the Party,the Party Central Committee with Comrade Xi Jinping at its core has vigorously promoted the construction of ecological civilization.The concept of a park city guided by the idea of ecological civilization conforms to the historical trend of the development of urban civilization in the world,and has important value in meeting the needs of the human settlement environment in the new era and shaping the competitive advantages of the city.As an ancient capital of the Six Dynasties,Nanjing has made a unique contribution to the preservation,continuation and development of China’s culture at an important juncture in the transition of Chinese history.Nanjing’s modern parks also have certain uniqueness along with their historical rise and fall.Therefore,Xuanwu Lake in Nanjing’s modern park was selected as the research object.By clarifying the historical change process of Xuanwu Lake,the current situation of park space’s participation of tourists was studied,and the future development direction of park renovation was speculated to provide theoretical data support for the construction of park cities.The thesis can be divided into three parts:research on the historical changes of Xuanwu Lake,the status of park participation by tourists and the design of the park renovation.First of all,by referring to ancient books and documents and graphic vectorization,understand the evolution process of Xuanwou Lake’s mountain-shaped water system,architecture and spatial function,introduce fractal theory,and summarize the changes of Xuanwu Lake in these three aspects through data analysis;then,use the Internet Big data,collecting the spatial distribution of tourists in Xuanwu Lake Park during the year,combined with field surveys and interviews and spatial surveying,summed up the differences in the participation of tourists in Xuanwu Lake Park at different times and different spaces,and Analyze the causes of the differences from three perspectives:function differences and spatial characteristics.Finally,by summarizing the history and current status of Xuanwu Lake,we can judge the future development direction of the park and propose transformation strategies for the existing problems.Through the study of historical changes,it has been found that due to the political,economic and social needs of various historical eras,Xuanwu Lake has undergone major changes in the mountain-shaped water system,gradually changing from the original single lake surface to the richness of continents,islands,embankments and bridges.The landscape and space fractal dimension continue to increase;the architectural forms in Xuanwu Lake form the traditional Chinese architecture of the Qing Dynasty to the period of the Republic of China and form a Chinese-Western architecture and eclectic style,to the establishment of New China to form a new type of architecture unique to China,and then gradually Towards modernization,the architectural space has changed from "private" to "public";in terms of functional nature,the landscape space has always been the focus of attention of design managers.The addition of various types of landscapes and leisure and entertainment facilities is the direction of the park’s changes in the past century.Sexual space has been valued in the changes,but the monumental space of Xuanwu Lake Park is scarce,and the history and culture are seriously ignored.Based on the analysis of the participation of tourists in Xuanwu Lake’s current space,it summarizes and proposes three major factors that affect the participation of tourists:spatial location,spatial functionality and spatial characteristics.The geographical location of the space is the main influencing factor of the difference in the participation of tourists.The geographical location is convenient and accessible,and the probability of tourists staying is greater;the participation of tourists in commemorative spaces is generally very low;when the spatial location difference is not large,the shape factor The smaller,the higher the participation of tourists.Based on the analysis of the history and current situation,Xuanwu Lake Park is recommended to transform and design the poor accessibility of some spaces and the low participation of tourists in historical monumental spaces.Strengthen its own historical and cultural functions and create unique historical and cultural scenic spots.By adjusting the planned route,the park forms a loop and improves the spatial accessibility of Liangzhou and Cuizhou;it is recommended to open the existing historical relic buildings to give the building new functions;add three new historical and cultural space nodes to the site.The interactive installation is combined with the venue’s rest facilities and landscape,which is entertaining and fun to increase the participation of visitors in the venue.By activating various point spaces,the entire historical and cultural area is activated in series.
