The Study On The Evolution And Development Of Medial Axis Space Sequence In Xi’an

Xi ’an urban Medial Axis witness to xi ’an for thousands of years ofdevelopment history, has a profound historical culture, is the center of xian city.Xi ’an urban Medial Axis in establishing and perfecting of xi ’an urban spatialorder has an irreplaceable role, reflect the characteristics of xi ’an city lifecharacteristic, is the continuation of traditional space structure and space structurein China. Xi ’an urban Medial Axis in space sequence, function composition hasobvious characteristics, reflect a certain historical period of the urban spacecharacteristic, is the important symbol of xian city spirit and national culture. Inthe history of xi ’an city development has an important role and influence.Xi ’an has several urban Medial Axis in history, layout has a significantinfluence on the modern xi ’an city. What has its change rule and relate to eachother? Its space sequence has what kind of characteristics, the affecting factors arebehind the have? In xi ’an today, for the construction of international metropolis,this reflects the Confucian thought of imperial power of xi ’an urban Medial Axisis there exist? Xi’an urban Medial Axis space will be how to develop?Construction of new district will have what worth? A series of problems before us.Based on the above problems, the author first on the Medial Axis and spacesequence of sorting and improvement of the concept, analyzing the characteristicof the law of development of domestic and foreign typical urban Medial Axis toreunderstanding urban Medial Axis and space sequence. Selecting representativecities at home and abroad and the axis of the change of space sequence analysis,for the evolution of the xi ’an urban Medial Axis space sequence development toprovide certain reference value. This paper takes time as the main line, by meansof literature research and historical research, the research of xi ’an urban Medial Axis changes, and to summarize its space sequence features. Scope of the presentsituation of the Medial Axis of xian city, the status quo of space sequencecharacteristics, the functions of the status quo, the present situation land usefunction and other related factors were analyzed, and combined with the naturalfactors, policy factors, social factors such as its influence on the development ofthe xi ’an Medial Axis, the dynamic development of xi ’an urban Medial Axischaracteristics and dynamic mechanism. The strategic development direction of xi’an international metropolis, analysis the development opportunity, behind the andthe scope of the Medial Axis of xi ’an city development and the evolution ofspatial sequence thinking and prospect.This paper takes time as the main line, to the historical documents andarchaeological data, history, geographical information, field survey and verifyeach other on aspects of material, study the western zhou dynasty in xi ’an cityaxis evolving law of spatial sequence. This study in two stages, namely, xi ’an cityaxis space sequence evolution and the development prospect in xi ’an Medial Axisspace sequence. With the formation of the Ming and qing xi ’an Medial Axis, thedevelopment of the modern xi ’an Medial Axis as the research focus.
