Abstract:

In the background of rapid urbanization, the expansion of urban functional space is causing widespread concern. The rapid expansion of urban area brings about a series of social and ecological problems. The focus of study is mismatch between expansion of urban area and service facilities. Our study makes use of land status maps and statistical information regarding Changchun City. It is also discussed that the features, effects and driving mechanisms of the functional space expansion of Changchun by citing a variety of models and spatial perspectives based on the availability of service space since 1995. ArcGIS and SPSS were used to reach and support our findings. The study’s findings are as follows: 1) The urban space of Changchun City expanded rapidly between 1995 and 2013. The pattern of urban expansion is still displaying the close field extension known as “circle mode”. Overall deviation problems between the city and service space have always existed. In the process of urban development and construction, the imbalance between functional space and urban space becomes more prominent. 2) The rapid expansion of Changchun’s urban space sparked a series of negative effects, including urban sprawl and an imbalance in urban functional space. However, expansion also promotes the evolution of functional space. The polycentric intra-urban structure has emerged in the metropolitan area. 3) This study also probes the dynamic mechanism of the evolution of the functional space of Changchun City, including administrative and socio-economic factors. We conclude macro urban development strategy results in mismatch between urban and service space, that policy reform promotes expansion of urban area, that socio-economic development is the source for the evolution of urban space. Through the establishment of regression model, the study shows that urbanization in terms of people and the improvement of urban living environments are social and economic core factors of the expansion of the essential connotation of urban functional space.
