摘要 基于美国SRTM-DEM数据,利用彩色晕染、密度分割与GIS空间统计分析等技术,并结合地质资料,通过地形高程、地表坡度
及地形剖面等分析手段,对阿尔泰山的构造地貌特征进行初步分析。研究表明,阿尔泰山脉平均海拔约1 790 m,平均坡度约21°
,其高海拔与高坡度的现代地貌特征,主要与强烈的断裂构造活动有关; 山脉严格受到以北西向为主的断裂构造活动的影响与控
制,其发育的构造地貌单元基本上呈北西走向特征; 山脉阶梯状地貌特征明显,共发育5级剥夷面,不同级剥夷面所处的海拔不一
样,同级剥夷面具有东北侧高于西南侧,山脉东、中段高于西段的特点。

Abstract :Based on American SRTM-DEM(90m) data and geological information and adopting color-dye, density-class
and GIS spatial statistic analysis technology,the authors studied geomorphological characteristics of the Altay
Mountain by means of topography-elevation analysis, surficial-slope analysis and terrain-section analysis.
According to the results of the study, the Altay Mountain has an average altitude of 1 790 m and an average
surficial slope of 21°, and the current geomorphological characteristics of high altitude and steep slope are
mainly attributed to strong tectonic activities; the mountain range is strictly affected or controlled by the NW-
trending fault activity, and hence the geomorphological cells mostly extend in the NW direction; the mountain
assumes obvious ladder-like modern geomorphology, and has developed 5-level denudation-planation surfaces with
different altitudes, with the northeast denudation-planation surface higher than the southwest surface, and the
east and central denudation-planation surface higher than the west surface.
