The invention provides a soil detection device based on laser-induced breakdown spectroscopy, which is applied to the technical field of soil detection, and comprises an unmanned aerial vehicle body equipped with a laser, a reflective telescope and a spectrometer; a laser emits high-energy pulse laser to irradiate a target soil area to excite plasma formation; and capturing an optical signal emitted by the plasma through the reflecting telescope, guiding the optical signal to the spectrograph, and finally performing soil analysis according to the spectroscopic data of the plasma collected by the spectrograph. Namely, the unmanned aerial vehicle technology and the laser-induced breakdown detection technology are combined, and compared with the mode that soil is transferred to a laboratory for analysis after being sampled in the prior art, the real-time performance of soil analysis and detection is improved, and large-range and continuous detection is achieved; in addition, plasma optical signals are captured and conducted through the reflection type telescope, the problems of visual angle errors, optical signal attenuation and the like caused by the flight height of the unmanned aerial vehicle are effectively solved, and meanwhile the signal capturing precision, stability and measurement efficiency are improved.
