The invention relates to a spacecraft autonomous delay telemetering method adapted to parameter characteristics. The method includes the following steps of: (1) classifying telemetering parameters of a spacecraft into a key parameter, a common parameter, an autonomous management alarm parameter, a command parameter, a constant value parameter, a key monitoring parameter and scientific test data according to the characteristics of the telemetering parameters; (2) processing the parameters respectively according to the characteristics of the parameters so as to optimize the storage resource and the downlink channel resource of the spacecraft; (3) distributing different storage areas for various delay telemetering data respectively by using a spaceborne computer to store; and (4) determining the delay telemetering download method by using the spaceborne computer according to the remote control command transmitted by a ground measuring and control station and storing and downloading the delay telemetering data.
