Description :
In this study, based on DEM and remote sensing images, multi-scale continental coastlines of China were extracted and the fractal characteristic was analyzed. It is shown that the continental coastline of China fits the fractal model; the scale effects with fractal dimensions of coastline have significant differences according to uplift and subsidence segments along the continental coastlines of China; the fractal dimension of coastline has significant spatial heterogeneity according to the coastline types. The length of rocky coastline is affected by scale more than that of muddy and sandy coastline. Since coastline is the conjunction of sea, land and air surface, the study of coastline scale effect is one of the scientific bases for the researches on air-sea-land interaction in multi-scales.
