Abstract

The paper study the question of population spatial structure change during the construction of international metropolis in Xi’an, to show the present spatial distribution of population in xi’an, and prompt the mechanism and trends of population satial structure change during the construction of international metropolis in Xi’an, as well as to forecast the population Spatial structure during the next decade.The first chapter of the article introduces the background and the value, define the concepts, point out the research methods, as well as to draw the techniques route map. the second chapter review and summarize the main research conclusion and methodologies in this field, advocated that further deeply study should concentrated in the follow aspects:to forcast the population space distribution, to choice the appropriate research space, as well as to excavate the population space information.The third chapter describe the population space distribution in xi’an By using two important concepts:the population density and the population barycenter. It points out that the population dense area is mainly in the six countis in the urban, especially the Xincheng, Beilin and Lianhu districts, which are around the belltower. By drawing the population density chart of counties in xi’an, applicate the GIS 9.2 software, find out the geometric coordinate of 49 blocks in the main city district, calculated the position of population barycenter is in the block named baishulin which is in the southeast near the belltower. During the nearest decade, the population barycenter tends to displace to the northeast orientation, which clarify that the northern new administration centre Zhangjiabu, and the north east new district Chanba have a more faster population increment than other districts in recent years, as well as the industrial district in the east suburb.Chapter 4 learns the "space" analysis methods from the geography to application gis software to cutting a map on the ring with equal measurements. and to count the area and population density of each block. then sum up the population in the same ring to calculate the population density of each ring. The population density model can be established with the rings’ population density datas. These models indicate that the characteristics of xi’an population spatial distribution is single center model, but the multi-centers structure is growing. Take the number of parameter, the perfect R square value, and the virtue of easy to explain into account, the paper choices the Clark model as the perfect one. Contrast the parameters of model in 2000 and 2009, the paper makes a preliminary assessment for the trends of population spacial distribution in xi’an, that the decline speeds of population is slower as the distanc away from the belltower, and the speed of population suburbanization is obvious speeding up.The chapter 5 analysis the mechanism of population spacial distribution change during the metropolis construction in Xi’an. The theoris include employment theory, the regional centres theory, as well as the preferences and choice theory. The analysis methods is to utilize the economic theories and models to study the changes of six major factors in Xi’an metropolis development, which will finally work on the population spacial distribution change. The six major factors, including population and employment growth, rising of living cost, changing of commuter way, consumption patterns, and spacial distribution of industry, as well as the promotion of the central leve of Xi’an. Each of the factors will affect the future population spacial distribution in the direction, strength, migrating populations constitutes, and the formation of new population spacial structure, to changes the population average age, the affiliated industy constitutes, the income and consumption capability in every block.The paper uses the analytical methods of data observation and statistics which is learned from the geology, also uses the logic analogy methods learned from ecnomics. As to synthetize the results from these two types of research methods, it draws a conclusion in chapter 6 by integrates the results from chapter 4 and 5 to forcasts the trends of population spacial distribution in.next decade by application the mathod of integration, consequence and synthesis, and to predict the space movement characters for citizen and tourists, as well as ratiocinates the evolution process of population spacial structure during the international metropolis construction.
