在Arc GIS10.0及GEODA软件的支持下,以赣粤闽客家聚居区为研究区,在县域尺度下选取2004年、2009年、2014年共3个年份的统计数据,运用引力模型及空间自相关分析方法,在考虑县城同时受多个中心城市引力作用的情况下,提出了引力首位度概念,分析了赣粤闽客家聚居区县域经济空间演化特征,划分了县域空间类型,并提出了县域发展的规划思路。研究结果表明:1)赣粤闽省际边界地区的县域经济空间集聚效果不明显,经济发展不均衡;2)县城受多个中心城市的引力时,可以根据引力模型及引力首位度将县域划分为空间聚集区和空间离散区两种空间类型;3)离中心城市距离较近且经济基础较好的县城可以撤县改区,空间集聚区可以打造小时经济圈,空间离散区可以建立新的区域发展联盟,同时受两个较大且大小相当的中心城市引力作用的县城可以考虑建成卫星城。
With the support of Arc GIS10.0 and GEODA software, taking Jiangxi, Guangdong and Fujian Hakka settlements as study area, the statistical data of three years in 2004, 2009 and 2014 are selected under the county scale. By using the gravity model and the space In this paper, the concept of the first degree of gravitation is proposed under the circumstance of taking into account the gravity attraction of the county and several central cities at the same time. Based on the analysis of the evolution characteristics of county economy in the Hakka community in Jiangxi, Yue and Min dynasties, the classification of county space is proposed and the county Development planning ideas. The results show that: 1) the agglomeration effect of economy in counties along the border between Jiangxi, Guangdong and Fujian is not obvious, and the economic development is not balanced; 2) When the county is gravitationally charged by several central cities, the county can be divided according to the gravity model and the first degree of gravitation As the space-gathering area and the spatial discretization area. (3) The county located close to the center city and good economic foundation can change the area to withdraw the area, the space gathering area can create the hourly economic circle, and the space discretization area can establish a new The League of Regional Development, a county town that is simultaneously dominated by two larger and equally sized central cities, can be considered as a satellite city.
