摘要
根据分形理论利用Richardson曲线法对海南岛海岸线进行了测量和研究.在1:1000000地图上对海南岛海岸线进行了测量,通过量规法和最小二乘法的数据处理,利用分维公式lgL(r)=(1-D)lgr+C得到了海南岛海岸线的分形维数,说明了海南岛海岸线的确具有分形的特征.此外还对海南岛不同区域的海岸线做了测量,首次得到了这些不同区域海岸线的分维,并分析了这些分维值间的异同.
Based on the fractal theory, Hainan island coastline was studied by using Richardson method. Using the equation lgL（r） = （1 - D）lgr ＋ C the fractal dimension of Hainan island coastline was obtained by measuring the coastline on a map of 1： 1000000 scale. The results showed that the coastline of Hainan island is fractal. In this paper, the coastline of different area of Hainan was also studied and the fractal dimensions of different area were obtained. It is the first time to obtain these fractal dimensions of the coastline in different area of Hainan. Difference of these dimensions was analyzed.
