Research Of Spatial Form Dimension Of Block Scale In Xi’an Ming City

Xi’an is the world famous historical and cultural city, Ming City is the core area of Xi’an city, its urban form showing the complexity and diversity, tradition and modernity scale scales coexist. Blocks are the basic units of the city, one of the cities most active element of vitality, is the cornerstone of urban existence and development. In this paper, Ming Town neighborhood scale of research focus for the excavation of Xi’an urban form characteristics, enhance the recognizability of Xi’an city, shaping the image of the city lay the foundation.Taking into account the Chinese localization and localization of the western urban morphology, this paper studies the formation of the regional characteristics of the urban block on the basis of the characteristics of Chinese cities. The traditional city block scale focus on object research and diachronic research, and as the core elements of urban development, "the main body" has not yet attracted enough attention, the system and function research in the urban block scale research has not yet been significantly, in the subject research, subject and object interaction research and other scale levels and synchronic research direction is still need to explore Street scale perception and change internal factors, from the aspects of the overall morphology, internal form and its elements, factors, analysis, induction and interpretation. The synchronic and diachronic evolution mechanism of the host guest interaction expands the research contents of morphology, from the aspects of the morphological function of daily living activities, the morphological effects of non spatial factors such as social economic structure, the active role of the main body, and so on.This article consists of three parts: The first part of the scale based on the laws of perception, to be tested to study the characteristics of neighborhood-scale psychological perceptual features; the second part based on elements neighborhood scale, three levels to record and study Area of the urban form of the current block : macro level- urban form, pattern blocks, the meso level- block size two-dimensional plane, the average height of the interface block, block block building density and floor area ratio, three-dimensional spatial pattern blocks, the micro-level- neighborhood near high aspect ratio space man, neighbor space width, and then select 10 typical neighborhoods, its physical scale depth studies were analyzed dialectical relations Area of the city district scale historical changes and the times; and the third part of the Exploration block scale deep body perception contact experience, explore the relationship between neighborhoods and neighborhood scale and form of human psychology and behavior. Urban scale, reached between urban form and the psychological line and a balance, coordination cycle. People by object objective form of perception, the formation of some kind of impression in the psychological, behavioral and feedback to the community, to collect material carrier will re-adjust the function information change thereby causing urban form.Today, Xi’an Ming City is facing the development again, the author from the city block scale level combined with its own research results and their own knowledge, for the Xi’an city space form of the continuation and development has made its own preliminary understanding and shallow suggestions.
