Representation and analysis of the complex spatial network relations are of great significance in fields such as Geographic Information System，spatial database, spatial data mining and intelligent inference. As the existing research achievements cannot be used to deal with the dynamic complex spatial network relations effectively in reality, in order to make up for the deficiency of existing methods, the dynamic complex spatial network relations is studied in detail. The predicate representation methods of the strict and extended complex spatial network relations are proposed respectively. The dynamic logical hierarchical relationship and dynamic migration relationship of the strict spatial network relation are given. Furthermore, this paper lay emphasis on the study of the dynamic conversion and adjacent relevance of the extended complex spatial network, and some instance analyses are provided. The research achievements in this paper is rather suitable for dealing with issues about the representation, error correction and forecast of the dynamic complex spatial network relations, therefore, the ability of spatial database to deal with spatial relations of complex spatial object has been enhanced.
