The characteristics of spring machanism in the Cheju Island were analyzed by statistical techniques. Basic characteristics, areal and altitudinal variations, and correlations of spring data were ivestigated. In this study, however, the subjects of the study are the 451 springs, the whole basin of Cheju Island devided into four groups. In this study, analyzed the spring phenomena on the basis of both the geologic elements and the topographic elements.
Also, the spring zone in Cheju Island are classified into three types that the mountain area, the middle area, the coastal area in spring distribution by altitude. The quentity of spring and variability show subvariety on the average according to Meinzer`s classification and the whole basin of spring shows various distributions from Third to Sixth.
