Definition of the Radiation Scope of the Logistics Park Based on Applying the Road Accessibility Analysis to a Potential Model

Rational planning and improvement on the operational efficiency of the logistics park depends on the precise of definition of the radiation scope of the logistics park, but there is still a lack of scientific and accurate theoretical method aiming at solving the definition of the radiation scope of the logistics park. Based on the traditional space division model such as potential model in the economic geography as well as giving full consideration to the important role the transport network playing in the logistics activities, the accessibility was introduced into the traditional potential model based on the Euclidean distance metric to modify the distance parameter, and the method of defining the radiation scope of logistics park based on applying the accessibility analysis to potential model was proposed. Finally, on the basis of GIS software, this method was used to define the radiation scope of the five logistics parks of the similar type in Sichuan province. It proved that the application of this method based on GIS software had the advantages of the scientific accuracy as well as the easy acquisition and operation of data, which reflected the higher application value.
