Being short of evolution mechanisms, theories of spatio-temporal representation and modeling have great challenges to
describe and represent the continuity and gradual geographical entities, still less deeper information retrievals and
knowledge mining. The spatio-temporal dynamic semantics, which contains geographical entities, changes of entities
and evolution mechanisms, is presented. According to the intrinsic process characteristics of dynamic entities, a
hierarchical semantics structure and process object sequences included by level are given. This paper describes the
process relationships and behaviors, and formalizes them into evolution operators, which subdivide into the process
recurrence operators and recurrence ones. Based on the object-oriented technologies, the evolution operators are
integrated into process object sequences, and a process-oriented dual representation framework on process objects'
recurrence and recursion (DRF-PORR) is presented as well. And finally, as a case study, the typical oceanographic
phenomena are taken to carry out the case modeling.
