为研究空间客运分布与交流的内在特性和运行机理,运用场论理论对空间客运联系进行了建模分析.提出了客流场的概念,并对客流场的场强、场势等特征量进行分析,探讨了单源和多源客流场的空间作用特性,对客流场的空间联系和空间位势进行建模和应用,并通过对比分析验证了所建模型的有效性.研究表明,可以通过客流场场强和势能来度量客流生成源对周围产生作用的潜力,客流场空间联系和空间位势模型可以较好地反映区域客运需求的联系特征和潜力特征,尤其是对城市连绵区域的空间客运联系分析具有较好的效果.

In order to study the intrinsic properties and operating mechanisms of the distribution and communication in spatial passenger transport, the model of spatial passenger linkage is proposed based on the field theory. The concept of passenger flow field is put forward and its characteristic quantities, such as field strength, field potential, etc. are analyzed. The characteristics of space interaction for passenger flow field with single source and multiple sources are discussed as well. The modeling and application of the space linkage and potential are studied in the spatial passenger transport and the model effectiveness is verified by comparison analysis. The study indicates that the filed strength and potential of the passenger flow field can measure the potential effect of the generation source on surroundings. As a result, the model can well reflect the connections and potentials of regional passenger transport demand, especially for the analysis of the spatial passenger transport connections in megalopolis regions.
