基于收缩视角的吉林省城镇化要素协调性测度

Measure the coordination of urbanization factors in Jilin Province from the perspective of shrinkage

侧重于城市收缩的视角,综合引用标准差椭圆、协调耦合度、灰色关联系数等计量模型,借助ArcGIS和SPSS分析软件,对吉林省人口、用地、经济城镇化演进特征与协调性特征进行了分析研究.结果表明:(1)近10年来吉林省城镇人口、建设用地、城市经济指标均呈现出收缩的端倪,并且城镇化要素成长的空间差异性显著;(2)中部城市群是各类城镇化要素集聚的重要承载地域,但各要素空间分布仍存在一定的差异,其中经济要素空间分布的集聚程度最高;(3)以长春为代表的中部地区各市县城镇化要素均显示出较高程度的协调性,研究时限内中部大中城市城镇化要素的灰色关联系数亦相对较高,城市发展整体呈现出增长态势,而边远小城市经济要素与人口、用地要素之间呈现出显著的不协调特征,部分要素收缩趋势明显,不同等级城市的城镇化要素协调性特征差异显著.

Taking the urban shrinkage as the entry point,this paper makes a comprehensive reference to the econometric models such as standard deviation ellipse,coordination coupling degree and grey correlation coefficient,and conducts an analysis on the urbanization evolution and coordination characteristics of Jilin Province s population,land use and economy by using ArcGIS and SPSS analysis software.The study found:(1)In recent 10 years,the urban population,construction land and urban economic indicators of Jilin Province have all shown signs of shrinkage,and the spatial differences in the growth of urbanization factors has significant.(2)From the distribution of SDE,it can be seen that the spatial distribution of urban population,urban construction land and urban economy is relatively consistent on the whole.The central urban agglomeration is an important bearing area of various urbanization factors,but there are still some differences in the spatial distribution of each factor,among which the agglomeration degree of spatial distribution of economic factors is the highest.(3)The“land-population-economy”coupling degree of the counties and cities in the central and western regions is generally higher than that in the eastern counties and cities.The urbanization factors of each city and county in the central region represented by Changchun showed a higher degree of coordination.The grey correlation coefficient of urbanization factors in large and medium-sized cities in central Jilin Province is relatively high,and the overall development of urban development showed a growth trend,reflecting a higher quality of urbanization development.There are significant inconsistencies between the“land-population-economy”factors in remote small cities,and some of them has obvious shrinkage trends.
