The invention discloses a method and a device for clearing a unit by adopting a multi-gear landslide climbing rate under a discrete condition. The method comprises the following steps: acquiring a unit landslide capability parameter and a unit climbing capability parameter; selecting a unit landslide capability gear and a unit climbing capability gear, judging whether the unit has cross-gear climbing and cross-gear landslide or not, and adopting different constraint processing modes; constructing a unit climbing ability constraint and a unit landslide ability constraint; and calculating the output of the unit at the t moment by combining the climbing and landslide constraint. According to the method, the problem that the unit landslide climbing rate cannot be adjusted along with the unit output change in the current electricity market clearing method can be solved, clearing results of the day-ahead market and the real-time market are more in line with a real scene, and the response capability of the unit to l
