The resources that enable cloud logistics have the characteristics of heterogeneity, discrete distribution, dynamics and autonomy. They have an influence on the efficiency of the integration and configuration of the resources. Based on fully considering the classification and the features of the cloud logistics resources, this paper establishes a uniform resource expression model. This model does not only transform the heterogeneity and discrete distribution into attribute or function information, but also transforms the dynamic and autonomy characteristics into capability information, achieved the mapping from cloud logistics physical resources to virtual resources. The use of ontology and web service technology encapsulated virtual resources into a Web service achieves the cloud service encapsulation of logistics resources. Finally, a transportation service application case has been used to validate the feasibility of the method.
