【摘要】：黄土高原数字地形分析以我国黄土高原为研究对象,基于该区域不同尺度DEM数据提取各类坡面地形因子及特征地形要素,并通过对各种地形因子和特征要素的自身特点、空间分异规律及各因子与要素之间的相互关系建立地学统计模型,从更深层次探讨黄土地貌演化及其空间分异规律,深化对黄土高原的认识。该文总结了黄土高原数字地形分析的基本理论与分析方法,从该区域的DEM数据模型、地形特征要素、地形信息图谱、地形纹理、沟壑信息图谱和地貌发育演化机理等方面对黄土高原数字地形分析的研究成果进行较全面地梳理与分析。可以看出,黄土高原数字地形分析已成为数字地形分析领域独具特色的研究方向,其中很多方法均已成为地貌计量学的重要研究手段。
[Abstract]:The digital terrain analysis of Loess Plateau takes the Loess Plateau of China as the research object. Based on the DEM data of different scales in this area, the terrain factors and characteristic terrain elements of various slope surface are extracted, and the characteristics of various topographic factors and characteristic elements are analyzed. The spatial differentiation law and the relationship between the factors and the elements are established to establish a geoscientific statistical model, and the evolution of loess landform and its spatial differentiation law are discussed from a deeper level. This paper summarizes the basic theory and analysis methods of digital terrain analysis in Loess Plateau, including the DEM data model, terrain feature elements, topographic information atlas, topographic texture, topographic information and texture of the Loess Plateau. In the aspects of gully information map and geomorphological evolution mechanism, the research results of digital terrain analysis on the Loess Plateau are summarized and analyzed comprehensively. It can be seen that, Digital terrain analysis on the Loess Plateau has become a unique research direction in the field of digital terrain analysis, many of which have become an important means of geomorphometrics.
