Study On The Relationship Between The Evolution Of Xi'an Urban Spatial Morphology And WeiHe River System

The study on urban morphology is the basic research of urban planning;the very core of which is the study about material form and rules of evolution. Through the study, we can provide scientific basis for planning the rational urban spatial structure, which is beneficial to give a fairly accurate forecast of urban future development.Through studying on the development of urban spatial morphology of Xi'an, Weihe River, which is one of the most important nature factors, has a important effect to the city form, the selection of the townsite, and the improvement of urban spatial morphology. Therefore the article tried to point out the rules of the evolution and obtain the developing patterns of urban space.The paper contains three parts: Putting forward the question, Analyzing the question and solving the question.The longitudinal and horizontal methods of research are used in the paper.The part of "Putting forward the question": The paper analyses the urgency of the study on urban spatial morphology of Xi'an and the importance of Weihe River system which affects the urban spatial morphology of Xi'an .Based on this, the paper draw forth the research subject.The part of "Analyzing the question": The paper laid stress on the evolution of the urban spatial Morphology of Xi'an which is influenced by Weihe River system. It makes a law of the evolution, through the analysis of the evolution course, the evolution stage and the evolution of internal and the external space.The part of "Solving the question": Drawing lessons from the regularity of urban evolution, the paper puts forward the direction for the development of Xi'an urban space and imagines the developing patterns of urban spatial which is based on Weihe River system.
