Spatial Characteristics Of Context And Its Protection And Inheritance Strategy In Linxia Historical Urban Area

With the rapid development of China’s social economy,urbanization has entered the middle and late stage,from incremental scale expansion to the new urbanization development stage of stock quality optimization.The development of cities has also ushered in an important period of urban renewal and protection.In recent years,the protection and inheritance of Chinese excellent traditional culture have been constantly mentioned by the central government,and the importance of protecting historical and cultural relics and enhancing cultural soft power has been increasing.How to restore the gradually lost characteristics of the city,protect and inherit the original tradition of the city and continue the urban context is a common concern of all sectors of society.The urban context can reflect the track of urban spatial development and the changes of many elements such as urban function and culture.It is also a key way to analyze the changes and characteristics of urban history.After the high-speed development stage,the urban land continues to expand,and the previous old urban areas have problems such as old facilities and imperfect transformation.With the decline of historical features and the disappearance of urban characteristics,the context space inheriting urban culture and history has become precarious,and the urban context has been cut and digested into scattered fragments in the city.In this way,there is a certain conflict between the protection of old urban areas and the renewal of cities,which has become an important factor hindering urban development.It has become an urgent task to explore and continue the urban context and enhance the sustainability of urban development.Linxia city,formerly known as Hezhou,is located in the southwest of Gansu Province.It is an important node on the south line of the West Gansu section of the ancient "Silk Road".It is also an important trade town on the "ancient tea horse road".It is known as "tea horse exchange market",western "dry wharf" and "hehuangxiong town".The region has not only rich Chinese traditional culture,but also profound Islamic culture.During the development period,the region has gradually formed a form of multi-ethnic,multi religious and multi-cultural coexistence.The long and splendid history and culture has precipitated rich cultural relics and unique details in the city.However,in the further development,due to the continuous improvement of the level of urbanization,the urban context is impacted,the urban characteristics are no longer significant,and the inheritance of traditional culture is in jeopardy.Taking the historical urban area of Linxia as the main research object,taking the phased characteristics of the development and evolution of urban context space as the clue,and drawing on the relevant research perspectives and methods of geography,sociology,urban morphology and typology,this paper systematically combs the "overall urban pattern","context space" and "context elements" of historical cities in different periods,Study the overall characteristics of urban space in different periods,identify the context space elements of historical urban areas,analyze the context element attributes and context space characteristics of different time sections,explore the temporal and spatial evolution mechanism of context space,and evaluate the value of context space,so as to show the internal characteristics of the city,So as to provide an effective method for the inheritance of Linxia’s context.Through the research,it is found that the evolution of the overall urban pattern is mainly manifested in the melting of the dominant urban boundary,the continuous integration of the outer space to the inner function between the city gates,and the historical axis has always been the main controlling factor of the development of urban space;The modernity transformation of the original city and the stable continuation of Bafang area have become the natural choice of urban development,reflecting the character and characteristics of the city;The disappearance and transformation of urban historical spatial elements are highly unified with the development of history,and show the important characteristics of function and spatial stability in inheritance.the research on the evolution of context space in historical urban areas shows that its mechanism is dominated by military defense and commercial trade demand from the end of Yuan Dynasty to the end of Qing Dynasty,to the main melody of internal and external political and military game during the Republic of China,and then to the main purpose of development after the founding of the people’s Republic of China.Various factors are intertwined,and culture,society and urban space interact to jointly promote the development and evolution of the city.
