中文摘要：

在多年野外调查的基础上，对衡山花岗岩地貌进行较为系统的研究。结果显示，衡山花岗岩地貌类型多样，景观丰富。衡山发育着典型的群峰——条形岭脊花岗岩地貌，花岗岩山峰密集成群，条形岭脊突出。峰顶主脊线长逾2×104m，众多列条形岭脊呈不对称肋骨状分布在主脊线东西两侧，从里到外呈阶梯状降低，共有4级阶梯，阶梯状地貌显著。此外，衡山断层构造地貌明显，水蚀地貌、崩塌堆积地貌以及石蛋地貌富有特色。研究认为，衡山花岗岩地貌代表着国内外一种典型的花岗岩景观，可称之为“衡山式”花岗岩景观，它是地壳运动、岩体性质、岩体构造、流水侵蚀等多种因素共同作用的结果；它集典型性、稀有性、完整性、自然性及优美性于一体，具有极高的科学价值、美学价值及旅游开发价值，并满足申报世界自然遗产的多条标准。

英文摘要：

On the basis of the field work that the authors have done for years, the granite landform of Hengshan Mountain in the middle of Hunan Province is systematically studied in this paper. There is typical granite landform in Hengshan Mountain. A crowd of granite peaks connect together to form a series of outstanding band-shaped ridges, of which the main ridge extend more than 20 km with many branch ridges distributed on its two sides, just like a set of costae. The mountain is also characterized by its four-step stairs landform. In addition, there are obvious fault structural landform, fluvial landform, colluvial landform and spheroidal stone landform in Hengshan Mountain. The landscape of the Hengshan is of typical granite landform and this kind of landscape can be called ＂Hengshan-style＂ granite landscape. The landform is the result from the common action of multiple factors, such as crustal movement, rock nature, rock structure and fluvial erosion and so on. Its typicalness, rareness and realness meet the standard of the World Natural Heritage.
