摘要:

利用改进的引力模型和潜力模型,结合GIS空间分析方法,从地级市和县域两个空间尺度分析了近20 a珠三角地区城市间相互作用的时空演变。结果表明:珠三角地级城市空间联系总体逐步加强, 并充分体现出广州的中心城市地位;县域尺度上,空间联系强度较大的主要是各地市市区之间及广-佛都市区的县市间和各地市市区与其所辖县市之间,其它县市间联系强度则较小;珠三角核心区内大部分县市之间联系总体呈逐渐增强趋势,核心区外的县市之间及其与核心区内的县市间联系强度有升有降,规律性不明显。广-佛都市区和深圳-东莞-惠州都市区的城市潜力较大且变动较大,对外辐射带动作用强,其它城市潜力相对较小且变化不明显; 珠三角城市潜力的区域不平衡态势明显,城市潜力的空间分异和空间辐射的特征与演变规律明显。

Abstract:

From the spatial scale of prefecture-level city and county area, this article establishes an evaluation index system of the urban comprehensive power of Zhujiang River Delta (ZJRD) urban agglomeration to analyze the urban comprehensive power in 1990, 1994, 2000, 2005 and 2009, respectively. Moreover, the spatial interaction level among the ZJRD cities and the potential value of each city are calculated using the improved gravity model and potential model. By these results, some GIS spatial analysis methods such as space thematic map expression method and space interpolation method, etc. are used to analyze the spatio-temporal evolution of the urban space interaction of ZJRD urban agglomeration in recent 20 years. The basic conclusions are obtained as follows: 1) The spatial contact among the ZJRD prefecture-level cities has been gradually strengthened as a whole, and the centrality of Guangzhou in the region is reflected. 2) At county-level scale, the linkage between urban area and counties under the same prefecture-level city, the linkage among urban districts of prefecture-level cities and counties in the Guangzhou-Foshan metropolitan region are strong, while the spatial linkage among other counties and cities is weak. The spatial linkage among most counties at the core region of ZJRD has been gradually strengthened as a whole, however, the spatial linkage among counties out the core region and the spatial linkage between the counties at the inner core region of ZJRD urban agglomeration and counties out the core region go up and down frequently all the way and have no discernible regularity. 3) The city potential values of Guangzhou-Foshan metropolitan region and Shenzhen-Dongguan-Huizhou metropolitan region are all strong and fluctuate pronouncedly. And the diffusivity of these two regions is also stronger than the other. The potential values of other cities are relatively lower and show no obvious fluctuation. 4) There is significant imbalance of the city potential between districts. The features and evolution laws of spatial differentiation and spatial diffusivity of the city potential in ZJRD urban agglomeration are obvious and unrest under stability.

Key words: spatial interaction, gravity model, potential model, Zhujiang River Delta urban agglomeration
