A method for determining a road type includes measuring, for a preset period, a magnetic field of an environment in which an electronic device is located to obtain a plurality of magnetic field values, calculating an absolute value of a difference between every two adjacent magnetic field values among the magnetic field values sorted in chronological order, calculating an average of the absolute values related to the magnetic field values to serve as a variation value for the environment, determining whether the variation value is smaller than a predetermined threshold value, determining that the environment is a surface road when the determination result is affirmative, and determining that the environment is a non-surface road when the determination result is negative.
