【摘要】：区域双核结构是由中心城市和港口城市组成的一种空间结构现象,基于既有的双核结构理论研究,构建刻画这一地理现象的数理模型。研究方法是以空间相互作用引力模型作为区位潜力的测度,构建基于中心联系、门户联系、自身对外联系三部分的综合区位潜力函数,并运用山东省作为案例进行实证检验。结果表明:综合区位潜力函数结合最大引力线设定参数,能够有效刻画两种极限情境下的区位潜力分布,得出山东省城镇体系空间作用格局的真实情形介于双核与多核两种极限情境之间的结论,并且在区域双核结构向多核结构演变的过程中,新的中心最易出现在与中心门户连线的中垂线上,因为这一区域受到中心城市和门户城市相对均衡的辐射。
[Abstract]:Regional binuclear structure is a kind of spatial structure phenomenon composed of central city and port city. Based on the theoretical study of binuclear structure, a mathematical model is constructed to describe this geographical phenomenon. The research method is to take the spatial interaction gravity model as the measure of location potential, and to construct the comprehensive location potential function based on the three parts of central connection, portal connection and self-external connection, and to use Shandong Province as an example to test the location potential. The results show that the comprehensive location potential function combined with the parameters of the maximum gravity line can effectively depict the location potential distribution in two kinds of limit situations. It is concluded that the real situation of spatial action pattern of urban system in Shandong Province lies between binuclear and multicore situations, and in the process of evolution from regional binuclear structure to multicore structure, The new center is most likely to appear on the vertical line connected to the central portal because the region is radiated by the relative equilibrium of the central city and the portal city.
