摘    要:在中国的经济地理格局中,信阳的地理位置非常优越,但其优越的位置并未转换为经济发展的动力.这个问题引起一些地理学家的困惑.要想回答这个问题,必须了解信阳的历史和地理特征.本文试图通过经验观察、空间对称分析和异速标度分析,揭示信阳的地理特殊性和经济发展的约束条件.主要判断如下:(1)中国城市对称分析表明,信阳市在中国的位置特殊:位居南北对称轴与东西对称轴的交点,即秦岭-淮河线与京广线的交汇处.(2)小麦产量与粮食产量的异速标度关系及其对数线性模型的预测残差分析显示,信阳地区在河南省的环境独特:信阳淮河以南六县属于河南省的异类.信阳经济发展落后的原因在于,计划经济时期因为地位不高没有国家和省投资,改革开放以后的工业化阶段因为缺乏矿产资源而没有崛起.但是,由于信阳位处中国城市网络的枢纽,待到第三产业真正成为中国产业的主体的时候,信阳将可能会因为交通和商贸的发展而迅速成长起来.

关 键 词:中国城市体系  地理对称  异速标度  残差异常值分析  信阳  河南

A Preliminary Analysis of Geographical Location and Economic Development Constraints of Xinyang

Abstract:Xinyang and its hinterland are unique in both Henan Province and China. Based on empirical observation,spatial symmetry analysis,and allometric scaling analysis,this paper is devoted to exploring the geographical location characteristics and economic development limitations of Xinyang city and region. The main findings are as below.First,Xinyang is located in the hub of China's urban network. The city is at the intersection point of the symmetrical axis of the East and the West and the axis of the North and the South of spatial distribution of Chinese cities. Second,agricultural production in Xinyang is a different category in Henan Province. The residual analysis of the allometric relation between wheat yield and total grain yield show that the six counties of Xinyang in the south of Huaihe River are all outliers. Through in-depth historical and geographical analysis,the main conclusions can be drawn as follows.( 1)In history,because of the frequent wars,the city of Xinyang could not grow steadily.( 2) Since 1949,because of the lack of mineral resources,the industry of Xinyang has not developed.( 3) In the future,due to special traffic conditions and geographical location,Xinyang will be very likely to become a metropolis along with the prosperity of China's third industry. This work is helpful for geographers to learn about Xinyang as city and region systems from the viewpoints of development.
Keywords:Chinese urban systems  geographical symmetry  allometric scaling  residual-based outlier analysis  Xinyang  Henan province
