河南省人口与经济空间格局分析

The Analysis of Distribution of Population and Economy for Henan Province

为了揭示河南省人口与经济空间分布状态,采用空间一致性指数与空间自相关对人口与经济的空间分布变化及地域关联性在县域与市域两个尺度上进行了分析。结果显示,河南省人口集聚大于经济集聚的县域数量大于经济集聚高于人口集聚的县域数量,且人口集聚大于经济集聚的县域主要位于河南东部、南部地区,而经济集聚高于人口集聚的县域主要位于中西部的郑州、洛阳、许昌及周边区域。市域中周口市、驻马店市人口经济一致性偏离程度最大,人口经济一致性程度较差,且较其他地区变化大。各县域人口经济一致性空间自相关系数逐年增加,显著的"高—高"与"低—低"的一致性关联模式在区域分布较广,分别位于东部与中西部地区,呈"带"状与"团状"分布。而人口经济一致性空间相互作用为"高—低"与"低—高"模式的数量最少,且变化较稳定。

To reveal the distribution of population and economy in Henan province, this paper uses the spatial consistency index and spatial autocorrelation to measure the spatial changing of population and economy , and explains the regional interaction patterns on the county and city scale. The result shows as follows： Henan province owns more counties which have bigger capacity of the concentration of population than the concentra- tion of economy, and these counties locate in the east and south of Henan province. The other type of counties which have less capacity of concentration of population than the former, and most of them locate in mid- west region of Henan, such as ZhengZhou, LuoYang, XuChang and so on,including their near regions. In the pre-fecture - level cities, the deviation for consistency index of Zhou kou and Zhu madian reaches the maximum, the coordinate of population and economy is low, and the difference is changing fast. The spatial autocorrela- tion index is increasing year by year, the significance of regions for the ＂High - High＂ and ＂Low - Low＂ pat-terns distribute to the Henan province widely, locate in the east and mid - west of region. These characters of distribution of region is compacted. On the other hand, the interaction of patterns for ＂High - Low＂ and ＂Low -High＂ are in minority, and they are quite stable.
