A severe low-power protection method for an unmanned aerial vehicle (10), and an unmanned aerial vehicle (10). The method comprises: firstly, when an unmanned aerial vehicle (10) is in a severe low-power protection state, acquiring ground environment information (S10); then obtaining landing safety determination information according to the ground environment information (S20); and then controlling a flight state of the unmanned aerial vehicle (10) according to the landing safety determination information, so as to realize safe landing of the unmanned aerial vehicle (10) (S30), such that where a battery of the unmanned aerial vehicle (10) is severely low in power, the probability of explosion is reduced, accidents where people are injured are prevented from occurring, and flight safety is improved.
