中国空间格局的规律认知与理论提炼

胡焕庸线、“T”型模式以及双核结构,可归纳为“一线两轴双核”结构,是不同时期中国人文地理学者对于中国空间格局的规律认知和理论提炼。胡焕庸线属于自然地理学地域分异规律在人文地理学中的延伸和拓展,遵循的是均质区域的基本假设;“T”型模式和双核结构则超越了地域分异规律的分析思路,遵循的是功能区域的基本假设。其中,“T”型模式是陆大道提出的点轴系统理论在中国的实践应用。从现象看,双核结构附属于“T”型开发模式,但后继研究实现了由特殊向一般的转化,完成了科学发现、机理分析、数学推导和实践应用的全过程科学研究,成为一个普适性较强的区域空间结构理论。从理论层面而言,分别基于均质区域和功能区域假设的胡焕庸线和“T”型模式属于空间分异规律的分析结果,属于地理学中的个例性理论;双核结构则属于符合一般科学意义上的普适性较强的理论。显然,胡焕庸线、“T”型模式和双核结构三位一体的分析,一方面表明中国是一个非常适合进行区域分析并在此基础上进行地理学规律和理论提炼的国家;另一方面,本文的研究可为区域空间结构规律的总结和人文地理学理论的提炼提供研究思路和方法论角度的启迪。

The rule cognition and theoretical construction of spatial pattern in China

"Hu Huanyong Line", T-shaped development model, and dual-nuclei structure model can be roughly summarized as a "one-line, two-axis, and dual-nuclei" structure. They are all rule cognition and theoretical refinements on spatial pattern in China which were proposed by Chinese human geographers in different periods. "Hu Huanyong Line" is proposed based on the regular recognition of regional differences. This is the extension and expansion of geographical differentiation laws of physical geography in human geography, following the basic assumption of homogeneous regions. The discovery of the T-shaped model of Lu Dadao and the dual-nuclei structure of Lu Yuqi transcended the analytical thought of regional differentiation laws. They follow the basic assumptions of functional areas. Among them, the T-shaped model is the practical application of the point-axis system theory proposed by Lu Dadao in China. From the phenomenon perspective, the dual-nuclei structure is attached to the T-shaped development model, but subsequent research has completed the transformation from special to general. It has accomplished the whole process of scientific research in scientific discovery, mechanism analysis, mathematical derivation and practical application. Eventually, it becomes a regional spatial structure theory with strong broad applicability. From the theoretical level, "Hu Huanyong Line" based on the assumption of homogeneous region and T-shaped model based on the assumption of functional region belong to the analysis results of spatial differentiation law, but they can also be called theories. They are individual theories in geography, while the dual-nuclei structure theory belongs to a more general and applicable theory in the general scientific sense. Obviously, the trinity analysis of the "Hu Huanyong Line", the T-shaped model, and the dual-nuclei structure theory shows that, China is a country that is very suitable for regional analysis and geographical laws and theories refinement based on this. The research in this paper can provide research ideas and method references for the summary of regional spatial structure laws and theory refinement of human geography.
