| The historical and cultural blocks have witnessed the social and historical changes in a certain period of the city,reflecting the local natural and human characteristics,and it is of great significance to the continuity of the historical context of the city and the display of local culture and characteristics.However,after a long period of baptism,the block often becomes the settlement of the life of the people at the bottom of the city.There are a series of problems,such as overpopulation,poor infrastructure conditions,environmental messy and private building phenomenon.The internal environment conditions have obviously not adapted to the life of modern people,and the block is gradually declining.And under such circumstances,the historical relics and historic sites inside the block are at risk of being destroyed at any time.As an important part of the city’s historical and cultural heritage,people have become more and more aware of the significance of protecting historical and cultural neighborhoods on urban revival and urban development.Governments at all levels attach great importance to the protection of historical and cultural blocks,and take a series of measures for protection and renovation.However,due to the deviation of the concept of protection and the drive of multiparty interests,a series of problems have emerged in the process of actual protection and renovation,such as the improper treatment of the traditional block pattern and style,the overexploitation of the block,the pure commercialization of the block and the lack of vitality in the street district,which all lead to the block.It can’t really go to revival.In view of the above problems,this paper,through the basic theory research and case study and analysis,comprehensively considers the urban development,the regional development and the development of the block itself,summarizes and constructs a more comprehensive and specific strategy for the protection and renewal of historical and cultural blocks in a global perspective,aiming at providing a basis for the future related research and for the present time.It will provide some references for post related practice,and promote the revival of historical and cultural blocks in China.The main contents of this paper can be summarized into three aspects.(1)Basic theory research: through the reading and reference of relevant literature,the author explains the related concepts of the protection and renewal of historical and cultural blocks,clarifies the object and direction of the study,and makes clear the purpose of this study through the summary of relevant research and practice at home and abroad.The main types and characteristics of historical and cultural blocks,the spatial composition and spatial characteristics of historical and cultural blocks are expounded,so that readers have a more comprehensive understanding of the historical and cultural blocks.On this basis,the contents of the protection and renewal of historical and cultural blocks are summed up into two aspects: the protection of the physical space environment.The protection and renovation(including the combing and integration of spatial pattern,internal and external transportation organization,space sequence organization,building protection and transformation,landscape system design)and the renewal and expansion of the block function make readers have a more systematic understanding of the protection and renewal of historical and cultural blocks,and study the following cases.The study of analysis and strategy provides a clear idea.In addition,the author makes a general description of the related theories of the protection and renewal of historical and cultural blocks(including urban design theory,organic renewal theory,place spirit theory,critical regionalism theory and environmental behavior theory),and analyses their historical and cultural streets.The guiding significance of protection and renewal will provide theoretical support for the next case study and analysis.(2)Case study and analysis: Based on the study of the related theories,the author selected three cases of protection and renewal of the more outstanding historical and cultural blocks in China-Chongqing guestan ancient town,Chengdu Kuan Alley and Zhai Alley,and South Song Royal Street in Hangzhou,and on this basis,each case protection and more The new concrete measures are analyzed in detail from six aspects: combing and integrating the spatial pattern,internal and external traffic organization,space sequence organization,building protection and transformation,landscape system design and block function renewal and expansion,and summarize the characteristics of each case,so as to protect and update the historical and cultural blocks of this article.The research of strategy provides a realistic basis.(3)The summary and construction of the strategy: the author puts forward the objectives and principles of the protection and renewal of historical and cultural blocks through basic theory research and case study and analysis,and on this basis,from the basis of the study,the paper combs and integrates the spatial pattern,the internal and external traffic organization,the space sequence organization,the protection and transformation of the architecture,the landscape system design and the street.The six aspects of regional function renewal and expansion are summed up and constructed the specific strategies for the protection and renewal of historical and cultural blocks:(1)The arrangement and integration of the spatial pattern,including the protection and improvement of the traditional street and lane form,the integration of the function of the block and the environmental and environmental resources inside and outside of the block;(2)The internal and external traffic organization,on the one hand,should be dealt with well The connection between the streets of the block and the outside city,the connection between the block and the public passenger system,and the setting of the parking lot improve the accessibility of the historical and cultural blocks.On the other hand,through the rational organization of internal streamlines to improve the accessibility and security of internal space;(3)Spatial sequence organization,according to the situation of the site,through the setting of nodes to create the space change of "starting,bearing,turning and closing",and creating different space atmosphere with the introduction of diversified formats and activities to avoid tourists.To produce monotonous and dull feeling,make it keep the interest of sightseeing;(4)The protection and transformation of the building,according to the historical value of the block building,the degree of preservation and so on,choose the proper way of treatment,and pay attention to the grasp of the scale relationship and the use of suitable materials and technology;(5)The design of landscape system,including street pavement,plant,store shop,landscape facilities and design,should draw inspiration from regional culture,display local culture and features,and coordinate the overall wind appearance in the form,material,color and other aspects.In addition,the design of service landscape facilities,such as trash cans,seats,etc.,should fully meet the needs of tourists in terms of form,size and quantity.At the same time,we should encourage the development of modern creativity and the use of suitable materials and technologies.In addition,through the preservation and protection of the historical remnants of the block,it can be displayed as a landscape;(6)The function renewal and expansion of the block function should be located in the three layers of urban development,regional and similar block division of labor,and the development of the block itself.The generation of daily life,cultural experience and leisure tourism demand,to co-ordinate the function of culture,commerce,tourism and other functions of the block,through the introduction of appropriate,diversified formats and activities to stimulate the vitality of the block. |
