中文摘要	地貌区划是研究自然环境空间分异的基础, 在区域地貌研究中具有十分重要的地位。本文分析总结了国内外地貌区划的相关研究成果, 系统探讨了地貌区划的具体步骤与方法、地貌区划的原则、各级地貌区划的依据和标准, 提出地貌类型组合和地貌成因类型的基本异同是各级地貌区划的依据。本文以中国1:400万地貌图等新资料为基础, 应用GIS方法, 结合中国三大地貌阶梯及其内部地貌格局的特点, 通过分析我国各地基本地貌类型组合的差异及其形成原因, 将中国地貌区划分为东部低山平原大区、东南低中山地大区、中北中山高原大区、西北高中山盆地大区、西南亚高山地大区和青藏高原大区6个地貌大区, 并分别简要论述了各大区的地貌特征。各大区内部又据次级基本地貌类型和地貌成因类型及其组合差异进一步分区, 全国共划分了38个地貌区。
英文摘要	According to research achievements of Chinese regional geomorphology over nearly 30 years, including landscape classification and landform mapping, this paper systematically discusses the specific steps and methods, principles and the standards for geomorphological regionalization. It is suggested that the basis and standard of geomorphological zoning at all levels not only include the similarities and differences of the combinations of geomorphology type together with the landform genesis, but also its dimension. Based on 1:4000 000 geomorphplogical map of China and the GIS technology, we made an analysis of reasons for the Chinese regional differentiation of the essential geomorphological types and their genesis and divided the whole China into six major geomorphological regions and 38 districts. Region I (eastern hilly plains) is located in the northern part of the low terrain unit of China, in which the largest plain areas of China are distributed. Plains and platforms are dominant and the fluvial accumulation landforms are well developed. This region includes seven districts. Region II (southwestern low-middle mountains) is located in the southern part of the low terrain unit of China, which is dominated by low-elevation hills and low-or middle-relief mountains with only 30% of its area occupied by plain and platforms. Fluvial geomorphologies are typical with a developed karst landform in Southwest China, which can be divided into five districts. Region III (central and northern middle mountains and plateau) is located in the northeastern part of the middle terrain unit of China, characterized by the plateau landform composed of the low-or middle-relief mountains, hills, platforms and plains. Loess landform is well developed. This region includes five districts. Region IV (northwestern middle and high mountains and basins) is located in the northwestern part of the middle terrain unit of China. It is composed of middle to high mountains interposed by flattened basins and is characterized by arid desert geomorphology, where mountains with basins are made up of plains, platforms and hills. This region can be divided into five districts. Region V (southwestern subalpine mountains) is located in the southern part of the middle terrain unit. With a typical karst landform, middle or high mountains with middle or high reliefs are widespread and are scattered by wide valley basins. This region includes five districts. Region VI (Tibetan Plateau) covers the high terrain unit of China. It is composed of plains and high mountains with elevations higher than 4000 m and 3/4 area of the region, and is characterized by glacier and periglacial landforms. This region can be divided into nine districts.
