A method for analyzing nerve fibers distribution is provided, including inputting a stimulation signal into a nerve tissue through at least two sensing and conducting electrodes, applying a stimulation signal ratio to control the stimulation signal using an electric current steering technique to electrically stimulate a plurality of nerve fibers within a plurality of stimulations areas of the nerve tissue； receiving a plurality of evoked compound action potentials (ECAP) using at least two sensing and conducting electrodes due to the nerve fibers electrically stimulated and computing a distance between the nerve fiber and the conducting electrodes including eliminating non-ideal effect caused by an electric potential attenuation factor, wherein the electric potential attenuation factor is a function of the distance between each of the conducting electrodes and the nerve tissue； and integrating and comparing the received ECAPs and analyzing the nerve fibers distribution of the nerve tissue.
