Summary:The invention discloses a space multi-point magnetic field intensity measurement apparatus and method based on single magnetic sensor. The space multi-point magnetic field intensity measurement apparatus includes a magnetic sensor probe, a magnetic flux aggregation array and a shielding cavity, wherein the magnetic sensor probe is arranged in the shielding cavity; a plurality of non shielding regions are arranged on the shielding cavity; shutter devices are arranged at the non shielding regions; the magnetic flux aggregation array includes magnetic flux accumulators; and any one magnetic flux accumulator is arranged on the outer side, of the non shielding region, corresponding to the shielding cavity. The space multi-point magnetic field intensity measurement method based on single magnetic sensor includes the steps: successively closing one shutter device when all the shutter devices are in the closed state, so that the signal periodicity of each magnetic flux accumulator passes through the non shielding reg
