| 摘 要： | 信息容量是计算机图形图像学领域的概念。文章将信息容量引用到地学分析当中,通过建立遥感影像信息容量的计算模型,对黄土高原不同地貌类型(塬、梁、峁)区遥感影像的信息容量和分形维数进行对比分析,揭示了信息容量和分形维数有很好的相关性,这就说明信息容量也能很好地反映不同地貌类型的地表特征,挖掘出了信息容量所蕴含的地学信息,为信息容量在地学领域的发展奠定了基础。

| Abstract: | Information capacity is a conception from the field of computer graphics.The paper recommended information capacity in geographic analysis by building computing model of RS image information capacity,and compared and analyzed remote sensing image’s information capacity and fractal dimension in different types of the loess plateau landscape(tableland,beams,Mao).To reveal the information capacity and fractal dimension has a good correlation.This means that information capacity could also fairly reflect the different landscape types of surface features,and digging out the geological information contains in the information capacity,and laid the foundation for information capacity in the development of geological field. |

| Keywords: | information capacity fractal dimension correlation coefficient |
