Research Of Spatial Form Dimension Of Legibility Of Blocks In Xi’an Ming City

Urban Morphology is the shape and form of settlements, reflecting the layout and structure of the urban space. Area of the city within the building sequence intensive and diverse types of neighborhoods to create the core of heterogeneous faces. Meanwhile, the functional requirements will be different this heterogeneity into the urban space. They not only come from the hands of designers in the city, but also the history of the city continued accumulation. Therefore, the space can form out of the city by the public good sense and deliver the value and significance is an important criterion for evaluation of its spatial quality.Understanding the physical environment is perceived by the "world" prerequisites exist, especially on the "place" of perception and experience of the people decide whether somewhere "settled." The overall perception and perception-based fragment abstract reorganization. Premise of a fragment of the whole city and the interior of rational knowledge that this fragment with recognizable physical form, ie be distinguishable. Therefore, this city block unit may be used as research objects to explore clear urban neighborhoods recognizability by rational and emotional, physical and spiritual and other aspects.This article is in the transformation of China’s urban and social background of the urban- block- discussed the framework of the city, research neighborhoods Area of the City Spatial Form in the Context of recognizability. First, from the perspective of the city urban scale under discussion may mean recognition, analysis of basic elements which can be identified in nature, and thus generalize Ming city urban level can be identified and limitations of the status quo, thereby introducing block recognizability, and explain the notion of what constitutes research path. Then based on the spatial behavior of the blocks were divided into type, formed residential district, non-residential neighborhoods, mixed neighborhoods are three types of blocks whole list, figure-ground, street corners and other analysis perspective, summarize the strength and characteristics of its recognizability. Cognitive behavioral differences due to differences arising from the research focus will shift whole neighborhood blocks inside, then extract typical neighborhoods internal research, with the Space Syntax analog local perception of space relations under the overall space, so the space can be cognitive structure relationship syntactic sense of character formula for expression. This premise, combined with cognitive behavioral questionnaire survey maps and analysis generated by the spatial cognition of the aesthetic tendency to change, can be integrated to achieve the typical district judge recognizability, which summed up the whole neighborhood and internal factors identifiable, and explore the relationship. Finally, the above analysis, three dimensions recognizability: behavioral, cognitive, aesthetic made good neighborhood recognizability for Area of the city of great significance.
