基于二维模式复杂度的DEM地形复杂研究

DEM Terrain Complexity Research Based on Two-dimensional Pattern Complexity

阐述了已有各地形复杂度描述因子的基础上,提出基于二维模式复杂度的栅格DEM地形复杂度因子的计算方法。计算陕西丘陵地区1∶5万DEM的结果表明,该方法可以有效地描述地表复杂地形的分布情况。

On the basis of elaborating existing terrain complexity describing factors, the calculation method of DEM terrain complexity factors was proposed based on two-dimensional pattern complexity. The hilly regions of Shaanxi 1 ： 50 000 DEM calculation results showed that the method can effectively describe the distribution of terrain complexity.
