Basis Of Mapping Of Elements Analysis In The Process Of Xi’an Urban Form Evolution Since 1990ies

Urban form as an interdisciplinary subject, research on urban morphology evolution on the discussion of the problems existing in the urban development has important significance. This paper by since the 90 s, xi ’an urban morphology evolution of the important factors in the process of the main research object, based on the xi ’an in recent years, the development strategy and urban planning, since the 90 s an important political decisions in xi ’an urban development, economic and cultural aspects of important measures the background. Starting from understanding urban plane shape, combined with geographical factors such as natural environment, economy, culture, learning basic the development of xi ’an city master plan, by using the theory of urban morphology, such as historical geography research of xi ’an urban morphology evolution since the 90 s have a comprehensive understanding, and by using analysis method combined with the Google Earth map important year end relationship mapping since the 90 s, through the consult literature material, combing tang chang ’an in ancient and modern times since Ming and qing chang ’an built urban morphology evolution of the relevant literature; At the same time, the xi ’an four-wheel overall urban planning study and master, has the history of the development of xi ’an city to make a clear and comprehensive understanding. Since the 90 s, xi ’an city expanding rapidly, urban morphology presents new characteristics. Through the collection of big events in xi ’an city construction since the 90 s, comb, compiled into memorabilia, determine what are the representative significance since 90 years, according to the Google Earth satellite image Mosaic, maps, the urban construction in the city map and terrain geomorphological map as the basis, science does determine the geographical spatial scope of this study. And describe each year built up area range, the urban road network, contour, drainage and other basic elements as the base of urban morphology evolution study graphic representation. And describe each year built up area range, the urban road network, contour, drainage and other basic elements as the base of urban morphology evolution study graphic representation. Debug the final rendering results, reproduction for subsequent single factor and studies provide scientific research basis. At the same time, according to the status quo of the development of xi ’an city, summarize the memorabilia from xi ’an city development and the national economy and social background, to discuss and determine the specific type of urban space as influence factor analysis in the form of xi ’an city since the 90 s, and these elements in the evolution of what changes have taken place in the process of its space form, and presented how to discuss the characteristics of the analysis. Final effect since the 90 s in xi ’an urban morphology evolution types of the urban space of living space, in the process of urban open space, the university campus, the plant as well as the cultural relics protection units. Come to the conclusion that since the 90 s external contour evolution characteristics of xi ’an urban morphology, and the internal structure including all kinds of the evolution of urban spatial morphology as a factor of research. Second, according to the related theories of urban morphology research, the status quo of xi ’an urban development, sums up the influence and effect on urban morphology changes external contour and internal structure of power factor, and the effect factors for urban spatial evolution of each power to make the corresponding concrete analysis. Emphatically analyzed influence since the 90 s in xi ’an urban form what are the specific elements of change, and how the effect of various types of urban space, respectively for xi ’an urban morphology evolution since the 90 s to do a full analysis and summary to the surface.
