| 摘 要： | Fractal theory was applied to a preliminary discussion of the fractal character and formation mechanism of the coastline of the bedrock coast of China on the basis of GIS ( Geographical Information System). Some significant conclusions were drawn : ( 1 ) The fractal dimensions of the coastline and linear structures of Liaodong Peninsula are 1.0093 and 1.0246 respectively, those of Shandong Peninsula are 1.019 and 1.021 respectively, etc. (2) The fractal dimensions of coastlines of Liaodong Peninsula, Shandong Peninsula, Zhejiang and Fujian-Guangdong tend to increase with the spatial change from north to south. (3)The regional linear structures( including faults)control the basic trends and fractal dimensions of coastlines as a whole in the regions of the bedrock coast of China : the more the controlling effect of linear structures, the smaller the fractal dimensions of coastlines. (4)The substantial constituents of coast and biologic function both play an important role in affecting the fractal dimensions of coastlines of Liaodong Peninsula,Shandong Peninsula, Zhejiang, Fujian-Guangdong and Taiwan Island.
