中国快速城镇化背景下城市功能空间迅速扩展引起了广泛关注。以长春市用地现状图和统计资料为数据源,借助ArcGIS和SPSS软件平台,引用多种模型基于服务空间视角研究了1995年以来长春市城市功能空间扩展的特征、效应与驱动机制。研究发现:① 1995~2013年长春市城市空间扩展迅速,扩展模式整体上以圈层式近域扩张为主,城市与服务空间整体的偏离问题始终存在,城市开发建设过程中服务空间明显滞后于城市空间的扩张。② 城市空间快速扩展产生了城市蔓延、功能空间失衡和城市功能空间的优化升级等效应。③ 行政因素和社会经济因素是城市空间扩展的主要驱动因素,回归模型结果表明人口城市化和人居环境水平的提高是城市功能空间本质内涵扩展的社会经济核心因素。 |

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. |
