| Under the wave of rapid urbanization,the phenomenon of dismantling the old new,then the city special features disappear,memory loss,loss of city spirit,urban space context fracture problem is increasingly serious,how to find the balance and integration of their protection and urban development and urban context,the development and protection,in order to protect the development is an important task of the current we face.As an important part of the city's cultural resources,the historic blocks record the city's development track,reflect the city's history and culture,and preserve the city's historical memory.Paper with rich historical and cultural resources,national characteristic but fracture crisis facing the space context in the process of development of ethnic minority regions-xi 'an hui historical block as the research object,through the analysis of the feature maps method,studies the spatial context features-"temple lane" structure and its spatial context evolution model,and on this basis for hui historical block protection and inheritance of the spatial context put forward specific methods and strategies.This paper mainly includes the following three parts:The first part,draw lessons from biological gene mapping,fingerprint analysis method,from the "synchronic" and "diachronic" perspective,to build the spatial context feature maps analysis method,through correlation analysis of explicit and implicit spatial context elements,summarize the dominant elements of ontology space morphology and image expression,extract the spatial context genetic factors,finally set up "image feature gene + context elements" reflect the characteristics of the spatial context and the sequence of time and space change rule of a information processing and expression method.In addition,the research tense and level of the feature map analysismethod of the spatial context of the historic blocks of the hui people are clarified,and the research model of the feature map analysis method of the spatial context is constructed.The second part firstly analyzes the historical evolution of the hui nationality in xi 'an(the period of ancestors,formation,development and decline,and further development)and the general situation of the development of the historical blocks of the hui nationality(population,economy and cultural heritage),and clarifies the connotation and characteristics of "sifang".Secondly,through the diachronic and synchronic two tenses,blocks and building two levels,"point-mosque","line-streets" "surface-residence" three main elements of ontology and hidden elements,such as politics,economy,culture and social relation analysis,build block level for hui historical block "temple lane" structure feature maps,building level "point elements-mosque" feature maps,"factor of line streets" feature maps,"surface elements-residence" feature maps;Finally,based on the analysis of hui historical block space context feature maps and contextual genetic factors of extraction,build their spatial context factors of dominant and recessive gene spectrum and summarize the space context in the different levels of evolution model block level space wenmai continuation patterns,construction level,some elements-mosque space wenmai continuation and integration mode,linear elements-the street space context variable and dislocation model,surface elements-residential space context model of fracture and collage.The third part,in view of the hui nationality historical block space context evolution model and context problems existing in the protection and development,by two blocks and building hierarchy,dot,line,face the space context factors continuation of ecological conservation,alienation and optimal variable genes targeted therapy of promote the protection and inheritance of the block space context,finally formed by blocks to architecture,from the point and line to plane,from to the recessive dominant form associated elements in multi-level,many elements,integration,the integration of the context of the protection and inheritance strategy. |
