经济活动的“点线面”空间区域占用形态及其分布规律初探

A Preliminary Study on the Spatial Pattern and its Distribution of the“Point,Line and Area”of Economic Activities

“点线面”结构是指经济活动的“点线面”三种基本占用行为和状态,其中,“点”是指城乡居民点体系,“线”是指城乡空间区域立体交通网络体系,“面”则是指农矿业和生态用地体系。“点线面”空间区域分布基本规律包括城乡区域经济分工合作分布规律、城乡综合立体交通网络分布规律以及农矿产业和生态用地分布规律。从数理分析的角度,探讨作为城乡区域经济学起点的经济活动对空间区域的占用行为与形态——“点线面”结构及其空间区域分布的基本规律,将有利于城乡区域经济分析和研究的不断深化。

The“point,line and area”structure refers to the three basic occupation behaviors and states of the“point,line and area”in economic activities,“point”refers to urban and rural residential system,“line”refers to urban and rural spatial three-dimensional transportation network system,“area”refers to the agricultural and mining and ecological land system.The spatial distribution of“point,line and area”includes the distribution of regional economic division and cooperation between urban and rural areas,the distribution of comprehensive three-dimensional transportation network between urban and rural areas,and the distribution of agricultural,mining and ecological land.From the perspective of mathematical analysis,this paper probes into the occupation behavior and form of economic activities to space area as the starting point of urban and rural regional economies——the structure of“point,line and area”and the basic law of its spatial distribution,which will be conducive to the deepening of urban and rural regional economic analysis and research.
