Research Of Spatial Form Permeability Of Neighborhoods In Xi’an Ming City

In the current urbanization process of rapid development background, the extension of the traditional urban space outside the main urban growth is facing enormous challenges. Urban spatial morphology showing a variety of forms, shape space fragmentation was evident. The urban space leads to the daily life of urban residents are isolated from public space value anomie, the loss of street vitality. The quality of urban life and urban space permeability related to urban space permeability urban environment affect behavior, it can stimulate the vitality of the city. Based on research of urban spatial morphology, urban neighborhoods Spatial Form of the base unit, view various types of neighborhood-scale morphological permeability. Permeable blocks form can contribute to the physical environment and the social functions of the city’s healthy development.Xi’an Ming City as the research scope. Ming City has a rich historical heritage, urban space form a complex, diverse, is facing the dual challenges of conservation and development, the city is very clear research value City area, contribute to a more complete understanding of neighborhoods in the urban space permeability form play a role and play a role.From urban and social transformation of China as the background, using the city-block- discussed the framework of the city, study Area of the urban dimension space form blocks permeability. Thus, this article on the city level and the level of permeability permeability to define the concept, from the synchronic and diachronic Context of its characteristics, influencing factors were analyzed, combining theory research status at home and abroad, the establishment of urban space permeability study the overall recognition know.Based on the city-scale analysis of urban spatial level permeability, Ming City Space Form Factors(urban space and function space, street space system, open space and activities) Situation Comprehensive Survey. By city function type divided into residential main functional blocks, the main function of the non-residential neighborhoods as well as outdoor open main functional blocks, the use of visits, a photographic record of more in-depth research and analysis methods of investigation. Analysis of Three main types of function space form permeability characteristics, and comprehensive assessment of the three main types of function space permeability.The neighborhood street level scale analysis permeability function blocks from the dimensions, the visual dimension, shape dimension three aspects to analyze blocks permeability. According to the theory of typology, the main function of the different types of blocks are classified research: the main function of the type of traditional courtyard residence residential neighborhoods, a collection of modern residential neighborhoods, as well as a collection of modern and traditional courtyard residence Street neighborhood; a non-functional types of commercial residential main functional blocks public service blocks include administrative offices, healthcare, education; the main function of the type of open outdoor parks, squares and neighborhoods. Use of space analysis, visual analysis, behavioral analysis of different types of function blocks permeability Comprehensive analysis of the status quo, summarizes blocks permeability characteristics and comprehensive evaluation blocks permeability. Finally, the main functional blocks of different morphological characteristics of permeability Ming Town analyze and summarize factors influencing the overall level of neighborhoods and neighborhood level affect permeability. Made good neighborhood permeable elements from the perspective of permeabilityArea of the city for the future development of great significance.Block "permeable" to promote the living environment quality is essential to the quality of urban living, the paper is purpose to have a deeper understanding of the city’s Old Town for resident, providing some basic information for the future formation permeability Old Town neighborhood, to guide urban development and urban design, and then the next city to protect and update to build a permeable find Countermeasure and suitability. When the history and culture surviving a brick face of the rapid urbanization of this situation, the protection and development facing the dual mode, in particular fusion pluralistic coexistence environment, based on these multiple diverse lifestyle and space complex superposition streets, and neighborhoods shape from the perspective of permeability to dig under the old city of the future value of dynamic urban development of the Ming guiding role.
