【摘要】：通过构建城市综合实力指标体系,运用主成分分析与聚类分析测算了福建省67个县级城市的综合实力并将城市划分为4个等级。在GIS平台中,计算局部莫兰指数,采用GIS栅格分析方法,利用场强模型对不同等级的城市腹地进行了划分。结果表明:福建省城市综合实力空间自相关特征表现为中部沿海的大城市集聚和北部的小城市集聚;福建省场强分布与700m等高线分布特征基本一致,场强值分布呈现明显的"一主一次"双轴线特征,次一级城市空间格局与高一级城市场强空间分布特征高度相关,高等级城市腹地呈垂直于海岸线的带状分布;地级城市腹地与行政区面积相似,但范围存在大量彼此交叉;县级城市腹地与行政区差异较小,城市腹地间以并存关系为主。
[Abstract]:By constructing the index system of urban comprehensive strength, the author calculates the comprehensive strength of 67 county-level cities in Fujian Province by principal component analysis and cluster analysis, and divides the cities into four grades. In the GIS platform. The local Moran index was calculated and the GIS grid analysis method was used. By using the field strength model, the hinterland of cities of different grades is divided. The results show that the spatial autocorrelation of urban comprehensive strength in Fujian Province is characterized by the agglomeration of large cities in the central coastal areas and small cities in the north. The distribution of field intensity in Fujian Province is basically consistent with that of contour line of 700m, and the distribution of field intensity shows the characteristic of "one main primary" and two axes. The spatial pattern of the second class city is highly correlated with the spatial distribution of the field intensity of the higher class city, and the hinterland of the high grade city is a zonal distribution perpendicular to the coastline. The hinterland of prefecture-level cities is similar to the area of administrative district, but there are a large number of intersecting areas. The difference between county urban hinterland and administrative district is small, and the coexistence relationship between urban hinterland is dominant.
