胡焕庸线简化解析几何模型与“胡焕庸线区位效应”——以中国大陆旅游市场潜力为例

胡焕庸线以其对空间的简化表达,描述中国人口分布东西悬殊的宏观格局。文章将胡焕庸线简化为地理坐标系中的线性解析几何模型——简称"胡焕庸线模型":Y=0.8697X-60.639,方便大数据背景下碎片化和非标准化对象空间相对胡焕庸线位置的判定。通过构建旅游空间潜力模型揭示中国大陆处于不同"胡焕庸线区位"地理单元的旅游市场潜力"胡焕庸线区位效应",分析胡焕庸线作为除距离因素外体现区域差异重要因素的有效性。这种体现在旅游市场潜力空间差异的效应,反映中国宏观经济地理区位的规律性现象,是经济地理区位的"胡焕庸线区位效应"。"胡焕庸线模型"—"胡焕庸线区位"—"胡焕庸线区位效应"构成基于中国国情的中国特色地域传统导向型区位理论。

Hu Line Location Effect: Perspective of Potential of Tourist Flows in China's Mainland

Hu Line, put forward by HU Huanyong eighty years ago, describes a macroscopic pattern of the great population difference between East and West China. Hu Line can be simplified to be expressed as linear analytic geometry model of coordinate system: Y=0.8697 X-60.639, called "Hu Line Model". This article constructs tourist flow potential model, analyzes the spatial pattern discrepancy of economic activities(tourism flows) and the potential structure of markets(customer markets), and reveals the "Hu Line Location Effect" of the tourism market potential in China's Mainland, which is in different geographical unit. The regional differentiation of population in China's Mainland attributes to the differentiation of social-economic spatial pattern and induces different potential of social-economic activities, which makes obvious discrepancy among the features of the tourism market potential curve in different cities."Hu Line Location Effect" also reflects China’s economic geographical locations pattern in macro scale. It can be concluded that "Hu Line Model"-"Hu Line Location"-"Hu Line Location Effect" structure constitutes the region-oriented location theory with Chinese characteristics under the national condition.
