The purpose of this study was to analyze the working time and the efficiency according to plot shape and plot size under the same conditions. We chose two stands which were relatively gently sloped end evenly distributed in number of trees and surveyed 198 plots, and 306 plots in each stand. 1. As to the time advantage of plot establishment method, the direct-four line establishment method was more favorable than the diagonal-line establishment method in a rectangular plot. 2. The method by Blumeleiss-$Me{\beta}$ trommel was more favorable than the method using a tape in a circular plot. 3. As to the time advantage, the circular plot was more favorable than the rectangular plot. Especially, the circular plot was twice more available than rectangular plot in small plot size, but enlargement of plot size gradually decreased time advantage of circular plot.
