City Image Evaluation Of Chongqing Industrial Heritage Based On Spatial Characteristics

With the advancement of urban industrial transformation and modernization,the renewal and reuse of industrial heritage has become an important means for many cities to enrich the connotation of urban image and enhance the image of the city.For example,Beijing 798 Art District,Chongqing erling second factory cultural and creative park and other projects have become new business cards of the city.In recent two years,the number of similar projects in China has been increasing rapidly,but there are some problems such as the lack of renewal project features,the similarity of urban image,etc.,which make the industrial heritage value fail to fully play and the resources with urban characteristics waste.Therefore,from the perspective of urban image,this paper intends to carry out evaluation and Research on Chongqing Industrial Heritage renewal project,which is of great significance to promote the effective renewal of urban industrial heritage.Firstly,the paper combs the literature related to industrial heritage renewal and urban image,defines the concept of urban industrial heritage,and summarizes the relevant theories and methods such as organic renewal;secondly,based on the literature and theoretical research results,the paper combs the development and evolution of Chongqing’s industrial history,analyzes the status quo and main renewal modes of industrial heritage;further explores the renewal project’s According to the characteristics of spatial distribution and the status of project renewal,Chongqing Industrial Heritage renewal projects are divided into four types of spatial clusters;the key factors of 9 significant driving projects renewal are identified by using spatial econometric model,and the reasons for the formation of spatial clusters are analyzed;thirdly,the mechanism of urban industrial Heritage renewal and urban image under the multi-agent effect is analyzed and elaborated The evaluation framework of urban industrial heritage renewal from the perspective of urban image is constructed,and the representative projects of different spatial clusters are selected for comparative analysis;then,the Internet social media data is collected as the source of public image perception,and the text analysis method of natural language processing is used for perception clustering and emotion analysis,so as to identify the perception and emotion of different spatial clusters Finally,the paper puts forward policy recommendations for different spatial clusters to provide reference for the decision-making,implementation and improvement of urban industrial heritage renewal,so as to promote the effective renewal of urban industrial heritage.The results show that:(1)there is a significant positive spatial autocorrelation in Chongqing Industrial Heritage renewal project,the "high value gathering area" is located in the core area of the main city,the "low value gathering area" is located in the far suburb counties,and there are "low value outlying area" and "non significant area" in the edge area and the Near Suburb Counties of the main city.(2)Chongqing Industrial Heritage renewal can form a unique image of the city,with a comprehensive emotional score of 69.30%.The overall public perception of emotion is relatively positive.However,the visual perception of Chongqing industrial heritage is strong,but the cultural connotation is insufficient,and the lack of cultural driving force is not conducive to the long-term development of urban image."High value cluster area" has high project vitality,obvious spatial function,and different perception and emotion among projects.The visual perception of "non significant area" is prominent,the controllability and accessibility are not strong,and the emotional score of each item is small.(3)For the four kinds of clusters of industrial heritage spatial distribution in Chongqing,nine targeted policy recommendations are put forward,such as "high value cluster area" renewal proposal using the renewal mode of embedded urban function repair,focusing on the development of cultural and creative industries and urban industrial upgrading.
