文献中常从分形角度来分析遥感图像。但是，有一方面未曾考虑，那就是图像可能为几个不同的分形过程的混合体。在这次勘查中，对已知分维数表面的太阳照射区和阴影区的分维数进行确定，并发现阴影区的分维数趋向于２．０。而令人惊奇的是，太阳照射区的分维数与其表面的分维数成反相关关系。
In the literature, often from the perspective of fractal analysis of remote sensing images. However, on the one hand, it has not been considered that the image may be a mixture of several different fractal processes. In this survey, the fractal dimension of the solar irradiation area and the shadow area on the surface of the known fractal dimension is determined, and the fractal dimension of the shadow area tends to be 2.0. Surprisingly, the fractal dimension of the solar irradiation area is inversely related to the fractal dimension of its surface.
