摘 要:以消落带为基础数据,采用网格法计算了不同水位及各段岸线的分形维数,对其分布特征和空间分布规律进行了研究。结果表明:(1)145 m水位岸线、175 m水位线和消落带整体形态的分维值D分别为1.1996,1.3216,1.3192;(2)消落带145 m水位线相对于175 m水位线和消落带整体形态而言,相对平直简单,与岸线实际情况相符合;(3)消落带网格单元分维值整体均值为1.24,最大值为1.40,主要分布在1.05~1.3之间。Taking the shoreline of the drawdown zone as the basic data,the grid method was used to calculate the fractal dimensions of different water levels and sections of the shoreline,and its distribution characteristics 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 1.1996,1.3216,1.3192 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.
