溢油-BL理论在港口经济腹地划分中的应用

The Applicationof Oil Spill and BL Theory on Port Economic Hinterland Division

为了更加准确地划分港口经济腹地的范围,在总结影响腹地范围划分的各因素基础上,结合港口腹地范围的地理分布特点,构建了基于水面溢油及BL(Binary Logit)理论的港口经济腹地范围划分模型,并具体分析了模型中各参量的意义及取值方法,最后,将厦门港的实际运行数据代入所建模型,计算其腹地范围,并用计算结果与厦门港传统经验腹地范围相比较,以验证所构建模型具备的可信度。

In order to divide the scope of the port economic hinterland accurately,on the basis of summarizing the factors that affect the division of hinterland,and in combination with the characteristics of port hinterland range,this paper builds a port economic hinterland range division model based on the theory of surface oil spill and BL analyses in detail the meaning of each parameter in the model. Finally,the actual operational data of the Xiamen port are applied to the model in order to calculate the range of its hinterland. The viability of the model is then proved by comparing the results with those obtained in a traditional way.
