摘要:

区域地貌研究是区域地理研究不可分割的重要组成部分。传统的基于DEM的数字地形分析方法,虽能较好提取各种地形定量因子,但由于分析算法的局限,很难实现对一个特定区域地貌的宏观形态特征与成因机理进行定量的分析。为此,近年来我国学者在该领域进行了系统的探索与创新实践,基于国家基础地形数据库多尺度、高精度的DEM数据,开展了基于DEM的区域地貌形态特征、地貌发育演化特征的研究。通过宏观形态指标分析法、地形特征要素分析法、地形信息图谱分析法等一系列方法,实现了对区域的地貌形态特征提取与分类、分区制图,取得了一批有重要国际影响的研究成果。在全国尺度以及黄土高原、青藏高原、西南喀斯特地区和月表月貌的区域数字地形分析方面,更彰显出研究的特色和优势。

Abstract:

Regional geomorphological research is an important part of regional geography research. In recent decades, digital terrain analysis has been widely used in regional geomorphology research. However, due to the limitations of the classic neighborhood analysis algorithm, it is hard to realize the quantitative analysis on the macroscopic morphological features. To solve this problem, Chinese scholars had made a lot of explorations and innovations. An overall review was made in this paper on Chinese scholars' contribution to the DTA research on macro terrain morphology analysis, topographic feature analysis, tupu analysis, landform evolution, landform classification and mapping. The research review shows that Chinese scholars' researches are closely followed by international frontier. The digital terrain analysis in the Qinghai-Tibet Plateau, the Loess Plateau and the southwest karst area highlights the regional characteristics and advantages of geomorphology in China, and has had an important impact in the international academic session.

Key words: regional geomorphology, digital terrain analysis, research overview
