摘要
借助长春市多期遥感影像、行政区划矢量图和社会经济统计数据,对九台撤市设区前后长春市的建设用地演变和经济发展情况进行分析,利用ENVI软件、GIS技术等多个手段,从长春市、九台区两级空间尺度揭示九台撤市设区对长春市空间扩展的影响。研究发现:1)撤市设区加快了九台区扩展进程,进一步影响长春市的城镇空间扩展方向与蔓延程度;2)撤市设区使得九台区和长春主城区产生朝向彼此的聚拢态势,两者空间距离逐渐拉近;3)撤市设区后九台区“极化效应”愈发明显,长春主城区与其均出现高密度聚集区;4)撤县(市)设区是城镇空间扩展的重要驱动力,主要体现在政策、经济和土地利用3个方面。
Removing counties(cities)into districts is one of the main modes of administrative division adjustment,which has an impact on the urban spatial structure.Using multi-temporal remote sensing images of Changchun,administrative division vector graphics and statistical survey data of social and economic conditions,this paper analyzes the evolution of construction land and economic development in Changchun City before and after Jiutai was withdrawn from the city and divided into districts.Utilizing ENVI software,GIS technology,and other means,this paper revealed the impact of Jiutai’s withdrawal from the city and the establishment as a district on the spatial expansion of Changchun City at the two-level spatial scale of Changchun City and Jiutai District.The research found that:1)Dismantling the city into districts accelerated the expansion process of Jiutai District,which further affected the direction and extent of urban spatial expansion in Changchun City.2)The decommissioning of the city into districts caused Jiutai and the main urban area of Changchun to converge towards each other,and the spatial distance between the two districts gradually narrowed.3)The“polarization effect”of the Jiutai District became more pronounced after the city was withdrawn and divided into districts,and high-density clusters appeared in the main urban area of Changchun.4)The division of counties(cities)into districts is an important driving force for urban spatial expansion,primarily reflected in three aspects:policy,industry,and land use.
