辽宁省制造业空间分布的多尺度分析

MULTIPLE-DIMENSIONAL ANALYSIS OF SPATIAL DISTRIBUTION OF LIAONING’S MANUFACTURING

空间尺度直接影响地理事物空间分布的研究结果。以辽宁省制造业企业为研究对象,利用格网分析、空间自相关以及基尼系数等探讨辽宁省制造业在多个空间尺度上的分布特征。研究发现:从行政区的视角来看,沈阳和大连是辽宁省制造业分布的两个核心城市,东西两翼地区制造业产值相对较低,主要城市中心城区的周边地区是制造业企业分布集中的区域;从连续空间尺度的视角来看,随着研究空间尺度的增大,辽宁省制造业的空间分布由多中心格局逐渐演变为以沈阳和大连为中心的双核心格局,其他部分地级城市仅在10~15 km的较小空间尺度下表现为制造业中心区;辽宁省制造业的空间差异程度与空间相关性的强弱表现出一定的尺度效应,6~54 km尺度是研究辽宁省制造业空间集聚水平的合适尺度,此空间尺度范围内辽宁省制造业均表现出极大的空间差异,以及一定程度的空间相关性。

Spatial dimension directly impacts the research of geographical objects distribution.This paper uses grid,spatial autocorrelation and Gini coefficient to study the spatial distribution features of Liaoning’s manufacturing with results showing that Shenyang and Dalian are two core cities for holding manufacturing with lower production in the west and east of Liaoning province.The surrounding areas of major city centers are the hubs of manufacturing.As research spatial dimension increases,multiple-center pattern of Liaoning’s manufacturing distribution turns into two-core pattern of Dalian and Shenyang,with other cities displaying manufacturing centers only under the scale of 10-15 km.The spatial difference and spatial correlation show scale effect with 6-54 km as an appropriate scale in studying the spatial concentration of Liaoning’s manufacturing,under which Liaoning’s manufacturing shows a large spatial difference and spatial correlation.
