| 摘 要： | 引入分形理论中的信息维数值作为衡量地形复杂度的指标,讨论了DEM地形复杂度对坡度提取的影响。结果表明,信息维数值能够较好地反映不同区域的地形复杂度;信息维数值越大,地形就越复杂,坡度提取的精度也就越低。

| Abstract: | Information dimension was introduced to describe terrain complexity,and the effect of terrain complexity on slope derivation from DEM was discussed.The result showed that information dimension reflected the terrain complexity of one region well;and the larger of the information dimension,the more complexity of the terrain,and the lower of the precision of deriving slope from DEM. |
