摘要: 以陕西省83个县域为研究单元,采用BP神经网络模型、GIS技术以及灰色关联模型对陕西省县域综合发展水平空间分异的格局、结构特征及其机理做了定量化评价与测度。结果表明:陕西省县域综合发展水平存在显著分异,县域综合发展水平总体均衡而局域不均衡,呈现出强者偏强,弱者偏弱,中等、中低水平相对集中的 “凸型”分布特征;在空间上总体表现为南—北方向递增,东—西方向“U型”分布,各类别县域空间分布具有明显的区位趋同性;空间形态基本呈“轴带”、“集聚区”、“轴带—集聚区”的型式分布,具有明显的等级分布特征。内部要素以及外部要素影响是造成陕西省县域综合发展水平空间分异的主要原因。

Abstract: Based on BP network model, GIS technology and Grey correlation model, this paper makes a comprehensive assessment of the socio-economic development at the county level, and reveals the characteristics and the laws of spatial disparities in the socio-economic development in Shaanxi province. The results show that the county level comprehensive development has a convex curve, which indicates that the strong trends stronger, and the weak trends weaker, with the middle and low level areas concentrated. The regional spatial structure presents that county level comprehensive development increases from south to north and shows a “U”-shaped pattern from west to east in space. In addition, the regional spatial forms have three types, namely the "Shaft", "Gathering area "and" Shaft-gathering area", and the distribution shows a clear hierarchy. Further studies suggest that internal and external factors are two main driving forces for the spatial disparities of county level comprehensive development.
