The invention is suitable for the technical field of televisions and provides a user desktop realizing method and system based on a television terminal. The method comprises the steps of a log collecting step, i.e., the television terminal records the user operation event of each service item in EPG (electronic program guide) and reports the user operation event to the television terminal; a counting step, i.e., the television terminal generates the user history operation data of each service item in a counting mode according to the user operation event ; a grading step, i.e., the television terminal performs comprehensive grading and sequencing on each service item according to a preset arithmetic and the user history operation data and sets a plurality of service items sequenced in the top to be desktop items; and a presenting step, i.e., the television terminal presents the user desktop comprising the desktop items. In such a mode, the user desktop realizing method and system based on the television terminal can intelligently generate and update the user desktop according to user habits and automatically recommend the service item to the user according to the preference of the user, thus simplifying the user operation.
