摘要
研究行政区划边界的空间形态特征,对研究区域历史,优化区域结构,提高经济水平都具有重要的理论和实际意义。利用分形维数、放射状指数和紧凑度3种定量测度方法,对河南省县级行政区划空间形态特征进行计算和分析,结合河南省社会经济发展数据研究发现,目前部分县级行政区划空间形态存在边界复杂程度高、行政中心边缘化和空间聚集性低等限制区域协调发展的问题。文中研究的方法可以为改善区划空间形态,优化区划边界形状和管理开发区域空间提供决策依据。
The study of the spatial morphological characteristics of administrative boundaries is of great theoretical and practical significance to the study of regional history,the optimization of regional structure and the improvement of economic level.In this paper,the spatial morphological characteristics of county administrative divisions in Henan Province are calculated and analyzed by three methods of quantitative analysis,such as fractal dimension,radial index and compactness.With the combination of the social and economic development data of Henan province,this paper finds that the spatial morphological character of some county administrative divisions restrict the regional coordinated development,such as highly boundary complexity,marginalization of administrative centers,and low spatial aggregation.Therefore,the method studied in this paper can provide a basis for improving the spatial morphology of the region,optimizing the boundary shape and developing of regional space.
