| 摘 要： | 地貌分类体系是地貌图研制的关键之一,本文在总结国内外地貌及分类研究的基础上,借鉴20世纪80年代的中国1∶100万地貌图制图规范,基于遥感影像、数字高程模型和计算机自动制图等技术条件,归纳总结了数字地貌分类过程中应遵循的几大原则,分析了它们之间的相互关系,讨论了数字地貌分类的各种指标:包括形态、成因、物质组成和年龄等,提出了中国陆地1∶100万数字地貌三等六级七层的数值分类方法,扩展了以多边形图斑反映形态成因类型,以点、线、面图斑共同反映形态结构类型的数字地貌数据组织方式,并详细划分了各成因类型的不同层次、不同级别的地貌类型。中国1∶100万数字地貌分类体系的研究,为遥感等多源数据的陆地地貌解析和制图提供了规范,也为《中华人民共和国地貌图集》的编制奠定了基础,同时为全国大、中比例尺地貌图的分类和编制研究提供了借鉴。

| Abstract: | Geomorphologic classification system is essential to geomorphologic research and mapping.Using the compiling methodology and standard of geomorphologic maps with a scale of 1∶ 1 000 000 in 1980＇s in China,based on the summarization of geomorphology,classification research at home and abroad,and the technology such as remote sensing image,digital elevation model（DEM） and computer automated cartography and so on,this research concludes and summarizes the principles followed in the classification process of digital geomorphology;analyzes the mutual relations hips among them;discusses various indexes of digital land geomorphologic classification： including morphology,genesis,material composition,age etc.The classification system puts forward numerical classification methodology of 3 classes,6 grades and 7 layers of digital Land geomorphology in China;presents data organization method of digital geomorphology,that is： morphology and genesis types represented by polygon map spot,morphology and structure type represented by point,line and polygon map spot together.Moreover,the article specifically presents the geomorphologic types of different layer and different level of various genesis types.The research of classification system of digital geomorphology provides a basis for the interpretation and cartography of Land geomorphology based on multi-source data such as remote sensing etc. |
