The Small City Land Utilization Spatial Variation And The Humanities Driving Influence Analyzes

At this stage of process of urbanization in China, the perspective of urban development has changed from pursuing competitiveness of a single city unilaterally to paying more attention to continuous development under the regional circumstances, emphasizing cooperation in order to realize regional economic integration. Regional economic integration contains three aspects, which are industry integration, production factor markets integration, and regional urban development integration. Thus requires reasonable adjustment of urban land use spatial structure urgently.Relating researches on land use spatial structure are still at the developing stage at present, and mainly concentrated on the large-sized cities'instead of small and medium-sized ones'. Given small and medium-sized cities playing a nexus role in the economic development and resources integration process, it is a useful method to study urban land use spatial structure about small and medium-sized cities(especially secondary cities).Form the inter-dynamic angle of city development, industry structure adjustment and land use spatial structure, planning systematic methodology as a thinking support as a whole, using the theory and method of regional economics, urban economics and economic geography, merging Linear correlation analysis method, on the basis of summarizing achievement of former researchers, comparative complete research on the evolvement of urban land use spatial structure ,the constitute of urban land use space, the evolving background, stages, characteristics and mechanism of urban land use spatial structure .Taking Jiutai city in Jilin province as an example, the analysis of the urban land use spatial structure and human driving force have been put out. This paper mainly contains :(1) the changes of Spatial structure of urban land use spatial structure in response to urbanization. (2)The mechanism and path selection urban of land use spatial structure. (3) The basic form and characteristics of urban land use spatial structure in small and medium-sized cities. (4) The demonstration research on the urban land use spatial structure of Jiutai city. The discussion of the evolving process and characteristics is carried out from one aspect as central city, and comprehensive analysis of all factors to provide Support and the basis to the choice of the direction of development of urban areas in Jiutai city. (5)The analysis of human driving force to the changes of Spatial structure of urban land use spatial structure in Jiutai city.Recalling the sequence and research thoughts of this paper,the following basic conclusions can be drawn:(1) The system of urban land use spatial structure is composed of urban land use spatial structure,space elements of urban land use and function of urban land use, which are in the most important position in urban land use spatial structure system.(2) We should be in light of the macro-regional context of urban development when we research the spatial structure of urban land use.(3) The research on the spatial structure of urban land use in Jiutai city can provide valuable references to the adjustment and distribution of prefecture-level cities in the Changchun-Jilin economic circle, simultaneously play an important role in adjusting the distribution and layout of the prefecture-level cities'land-use structure in the Changchun-Jilin economic circle.(4) The features of the changes of urban land use spatial structure mainly contains: the extensive expansion of Built-up area is rapid; the internal structure of land for construction is becoming more reasonable; functions of land-use spatial structure have formed gradually.(5) The direction of urban development can be summarized as"expanding in the south, controlling in the north, optimizing in the east, limiting in the west". The city space has adopted the layout mode as"a primary region and a secondary region". The urban spatial structure can be designed as"four centers and three districts".(6) The way of Evolution of urban land use spatial structure in Jiutai city can be obtained by the researching on the driving force of the evolvement of urban land use spatial structure.In the process of research on the urban land use spatial structure evolvement, a lot of theory foundations and demonstration resources are gathered to make theory and practice integrated closely.Besides,in favor of reducing the gap existing in current study on urban land use spatial structure, and providing some reference to decision-makers on land resource integration among cities, the research scale of this paper is mainly focused on small and medium-sized city, which is the primary innovation of this paper. Meanwhile, Linear correlation analysis on land expanding orientation of Jiutai central city has been carry out, which enhanced the reliability of prediction and therefore comes to be another innovation of this paper.However this paper didn't go deep enough in the part of demonstration that the results appeared to be a little coarse inevitably, so further communication with related crew is still needed. And many data is lack of unitive statistic caliber, although necessary adjustment has been made, the randomness still exists due to individual limited capacity during making analysis and prediction in the demonstration part, so more efforts should be made in the future.
