Research On The Micro-renewal Of Public Space In Residential Historical And Cultural Blocks

The historical and cultural district is a microcosm of the city’s long development process.The "living" as its main function has witnessed the changes of the city in different eras,recorded the traces of urban development,is the material carrier of the city’s historical memory,and is also the cultivator,place of growth and inheritance of local cultural customs.The block entity displayed in concrete form retains a specific historical style.This unique external characteristic developed over time and the various behaviors and social activities of the people living in the block in the public space constitute the relationship.The historical and cultural block,an activated urban development museum collection,plays a very important role in studying and understanding regional culture,carrying forward and inheriting the spirit of high-quality culture,or serving as a place for the emotional return of modern urbanites.However,in the current wave of protection,renewal and transformation of historical and cultural blocks,multi-party investment entities driven by interests seek economic benefits.The development trend of historical and cultural blocks is to obtain high profits,which is mainly reflected in the general and pure current historical and cultural blocks.The phenomenon of commercialization or over-tourism pays little attention to the daily living space environment of the aborigines who live and live in it for a long time.These once glorious "residential" historical and cultural blocks have deviated from the track in the fast-paced urban development and have been neglected.The living environment and quality of life of residents are out of balance or even out of touch with modern life,leading to the gradual decline of the blocks.How to update the public space environment of historical and cultural blocks on the basis of protecting the overall historical features to improve the quality of life of block residents and maintain authentic social relations is an urgent need for in-depth research.This paper takes the historical and cultural block of Chengjiang Old Street in Beibei District of Chongqing as an example to study the residential historical and cultural blocks that are currently less concerned.Starting from the public space,research on the spatial form and constituent elements of the block,sort out the public space with historical and cultural value in the historical and cultural block of Chengjiang Old Street,and focus on using the PSPL research method to analyze and evaluate the environmental quality and public life characteristics of the block?s public space,Derive the relationship between the environmental quality of public space and the daily life of the aborigines of Chengjiang Old Street,and based on this,combined with the urban micro-renewal concept under the background of current stock planning,propose the renewal of the public space in the historical and cultural district of Chengjiang Old Street Principles and goals,and put forward practical renewal strategies from the planning management and design level.It is hoped that this will be used as a trigger to improve the overall spatial environment of Chengjiang Old Street,improve the functions of public space,and meet the needs of more public life,so as to activate the context of social relations and maintain the authenticity of traditional life images and historical and cultural values of historical and cultural blocks.Start with the basic overview of the historical and cultural district of Chengjiang Old Street,expounding its characteristics and historical and cultural value.Further analyze the types and constituent elements of the public space in the block.Secondly,based on a preliminary visit to understand the basic status quo of Chengjiang Old Street,the PSPL research method is mainly used to investigate and analyze the environmental quality and public space behavior characteristics of the public space in the historical and cultural district of Chengjiang Old Street.Finally,based on the previous theories,cases and research and analysis results,a micro-renewal strategy for the public space of Chengjiang Old Street is proposed.The research results show that the overall public service facilities and municipal infrastructure in Chengjiang Old Street are aging and dilapidated,and need to be improved and updated;the environmental quality of public space and public space behavior activities show that the block roads are congested,the visual environment is broken,and the historical features are corroded.Serious,insufficient public space facilities,lack of rest and entertainment facilities in the space,simplified activity types,and insufficient overall vitality.In response to the above problems,this article determines the integrity,authenticity,continuity,public participation,aesthetics and micro-renewal principles that should be followed in the process of public space renewal in Chengjiang Old Street;it proposes to preserve the characteristics of the block and improve the quality of the space.The three basic goals of restoring the vitality of public spaces;from the planning management level and the design level,the renewal and optimization strategy of the historical and cultural district of Chengjiang Old Street is proposed,indicating that the overall planning of the Chengjiang Old Street should be implemented at the planning management level,the protection system should be improved,and the investment subject should be activated;At the level of design renewal,it is necessary to repair the spatial structure of Chengjiang Old Street,improve the space interface environment of the block,create a historical context,and enhance the multiple functions of the space.
