The associative relation of spatial-temporal objects of multi-granularity describes the relations and mutual effects among objective entities in real world. It is the expression of entity relationship and mutual effects. According to its different describing subject, the associative relation can be divided into temporal relation, spatial relation, attribute relation and comprehensive relation. This paper begins with the background of pan-spatial information system, elaborates the basic conception of the associative relation of spatial-temporal objects of multi-granularity , and defines its formalized expression and classification. We also illustrate and analyze the construction and administration of associative relation, the applicative scene of static construction method and dynamic construction method. The associative relation maintains the consistency and linkage of the digital world through constraining effects and behavior conduction. Thus, this paper gives a brief illustration of constraining types and definition of associative relation and relation-behavior conduction mechanism.
