基于GIS势力圈测度的南京市行政区划调整合理性分析

当前行政区划调整评价方法以定性的、经验式的判断占主导地位，缺乏有效的定量分析，其合理性存在争议.本文基于地理信息系统（GIS）势力圈技术，将基于势力圈测度结果得出的南京市行政调整方向与实际调整方案进行比较，分析南京市3次行政区划调整的合理性.结果显示，基于势力圈测度的行政区划调整方向与实际行政区划调整方案基本吻合，说明了实际调整方案的合理性.值得指出的是，行政区划问题属于上层建筑范畴，与政治、文化、历史等因素密切相关，不能完全按照定量分析的结果来进行具体的划分.

Analysis of the rationality of Nanjing's administrative division adjustment based on a GIS spatial analysis

Whether the administrative division adjustment is reasonable is not only directly related to the allocation of social and natural resources, but also to economic development and social stabilityin a region. A scientific approach to analyze the reasonableness of zoning adjustment is of enormous importance. However, the current regional administrative division adjustment in Nanjingis dominatedby qualitative evaluation methods and empirical judgmentas well as a lack of effective quantitative analysis, which has resulted in uncertainty in the analysis process. Therefore, based on geographic information system (GIS) technology, Nanjing''s administration adjustments calculated from the hinterland model were compared with the actual adjustments since 1995. Next, the rationality of Nanjing''s administrative division adjustmentwas evaluated. The evaluation results showed that the administrative division adjustment was consistent with the results calculated from the hinterland model, which illustrates the rationality of the actual adjustments. However, it is worth noting thatadministrative divisionproblems concern superstructure, in addition totheeconomic level, geographical scope, and populationsize of the area, which are alsoclosely related to political, cultural, historical, and other factors. Itcannot completely relyon the results ofquantitative analysis. The specificneedsofthe township should be consideredin a subsequentstudy.
