The invention relates to a method for searching a data target on basis of a spatial-temporal database. The method is characterized by comprising the following steps: according to the temporal state and the spatial state of a target to be managed, performing modularization on the managed target; according to a management model of the target to be managed, setting a specific attribute which is described by using a natural language, of the target to be managed; on the basis of the type of the management model of the managed target, and a temporal attribute and/or spatial attribute which is defined by modularization and is described by using the natural language, performing retrieval, so as to confirm the operation state of the managed target. According to the spatial-temporal database, data information of production monitoring management is described by using three sections of times of history, real time and planning, a user does not need to master a computer language, but only with a spatial-temporal meta language, spatial-temporal data of the managed target can be retrieved and understood, and the spatial-temporal operation state of the managed target can be understood, namely both computer content can be saved and management is facilitated.
