Zusammenfassung:	This application discloses a slope detection apparatus and method based on distributed optical fiber sensing. The apparatus includes: optical fiber measuring units arranged inside a slope and configured to measure acceleration time sequences of a plurality of state parameters of the slope; a demodulator, where the demodulator is connected to the optical fiber measuring units and configured to receive the acceleration time sequences of the slope; and a terminal device, where the terminal device is connected to the demodulator and configured to perform multi-domain coupling analysis on the acceleration time sequences so as to generate a feature cloud map of the slope, perform sub-item detection on slope stability state based on the feature cloud map and preset multi-domain feature parameter indexes so as to obtain a sub-item detection result of the state of the slope.
