Taking the shoreline of the drawdown zone as the basic data,the grid method was used to cal-culate the fractal dimensions of different water levels and sections of the shoreline,and its distribution char-acteristics and spatial distribution rules were studied.The results show that:(1)The fractal dimension values D of the overall shape of the 145 m water level shoreline,175 m water level and the leveling zone are 1.199 6,1.321 6,1.319 2 respectively;(2)The 145 m water level in the leveling zone is relative to the 175 m water level and the leveling zone.In terms of the overall shape,it is relatively straight and simple,consistent with the actual situation of the coastline;(3)The overall mean value of the fractal dimension value of the grid cells in the ebb and flow zone is 1.24,and the maximum value is 1.40,mainly distributed between 1.05～1.3.
