【摘要】：本研究以吉林省中部城市群为研究区域,运用城市流理论模型与GIS的空间分析方法,对2003~2010年研究区的城市流强度与结构进行了测算,定量分析了城市流强度的时空变化特征,并采用多元回归模型对影响城市流强度的相关因素进行探讨。结果表明:(1)2003~2010年吉林省中部城市群各城市的城市流强度呈现不同程度的增加,但整体的集聚和辐射能力较弱,空间联系较为松散,长春市的核心带动作用需进一步提高;(2)城市流强度整体上形成了一种以长春市为中心的圈层式结构,且区域内空间差异显著,呈现北高南低的格局;(3)城市流强度结构特征表现为城市总体实力与城市流倾向度的关系尚不协调;(4)第二产业对城市流强度的影响大于第三产业,吉林省中部城市群仍处于以工业增长为主导的发展阶段,第三产业发展相对比较落后。最后,提出了吉林省中部城市群各城市之间增强区域经济联系与提高城市流强度的相关对策。
[Abstract]:Based on the urban agglomeration in central Jilin province, the intensity and structure of urban flow in the study area from 2003 to 2010 were measured by using the urban flow theory model and the spatial analysis method of GIS. The spatial and temporal characteristics of urban flow intensity are quantitatively analyzed. The multivariate regression model is used to study the related factors affecting the intensity of urban flow. The results show that: 1). From 2003 to 2010, the intensity of urban flow in central cities of Jilin Province increased in varying degrees. But the agglomeration and radiation ability of the whole is weak, the space connection is looser, the core driving effect of Changchun needs to be further improved. (2) the intensity of urban flow has formed a kind of circle structure centered on Changchun, and the spatial difference in the region is significant, showing the pattern of north high and south low; 3) the characteristics of urban flow intensity structure show that the relationship between urban overall strength and urban flow tendency is not in harmony; The influence of the secondary industry on the intensity of urban flow is greater than that of the tertiary industry. The urban agglomeration in the central part of Jilin Province is still in the stage of development dominated by industrial growth, and the development of the tertiary industry is relatively backward. This paper puts forward the relevant countermeasures to strengthen the regional economic connection and enhance the intensity of urban flow among the cities in the central city group of Jilin Province.
