英文摘要	Spatial, temporal and attributive characters are the three basic characters of spatial entities. Temporal attributes change over time. Research and Modeling on temporal attributes' temporal semantics are important in spatiotemporal data modeling field. In this paper, in the form of algebraic relation, an attributive function is proposed, based on which, the temporal semantics of independent variable, domain of definition, function's relation and function's value are analyzed, and the algebraic descriptions, definitions and classifications of them are presented. At last, a classification with 20 types of temporal attributes are motivated which is able to offer advanced support for data modeling on temporal attributes, research on operation and query language, and presentation techniques in temporal geographical information system (TGIS).; EI; 0; 9; 1097-1102; 38
