Zusammenfassung:	Provided are a method for measuring an amount of snowfall and an apparatus for measuring an amount of snowfall using a single laser distance meter. The apparatus for measuring an amount of snowfall according to the present invention comprises: a laser distance meter; a step motor including a rotary shaft; a mirror connected to the rotary shaft of the step motor such that the mirror is tilted at a predetermined angle from the plane vertical to the rotary shaft, so as to reflect a laser beam from/to the laser distance meter; and a control unit for controlling the laser distance meter while rotating the mirror by controlling the step motor so as to measure a distance. According to the present invention, the mirror for reflecting the laser beam rotates by being slightly tilted, and therefore, measurement of an amount of snowfall at multiple points dispersed along the circle on the surface of the snow is enabled.
