The invention particularly relates to a variable-parameter satellite vibration isolator and a vibration isolation method. The vibration isolator comprises a thermistor, a metal shell, a resistance wire, a filling polymer, a connector, an upper fixed support, a heat insulation assembly, a lower fixed support and a wire. The filling polymer, the connector, the upper fixing support and the lower fixing support are all of an annular structure, the outer surface of the connector is connected with the inner wall of the upper fixing support, the outer wall of the upper fixing support is connected with the inner wall of the upper half portion of the filling polymer, and the outer wall of the lower fixing support is connected with the inner wall of the lower half portion of the filling polymer. The inner wall of the lower fixing support, the bottom of the connector and the bottom of the upper half portion of the filling polymer define a bolt installation cavity, a metal shell is arranged on the outer wall of the filling polymer, a resistance wire is wound outside the metal shell, a heat insulation assembly is arranged outside the resistance wire, and the satellite control unit is connected with the thermistor and the resistance wire through two wires.
