摘　　要：基于最新完成的中国1∶100万数字地貌数据库和山西省地图数据,利用GIS空间分析和数理统计分析方法,获得山西省多级行政单元的数字地貌类型分布特征。研究结果表明:山西省平原、台地、丘陵和山地4种地貌类型分布面积占全省总面积的比例依次是19.10%,15.77%,14.72%,50.41%;在山西省的11个地级市中,除了朔州市以平原地貌分布为主、运城市以台地地貌分布为主,其他9个城市中分布最广泛的地貌类型均是山地;在山西省的108个县中,平原作为最重要地貌类型的县有19个,台地的有17个,丘陵的有12个,山地的则有60个。Based on newly-achieved digital geomorphologic database in China at 1∶1,000,000scale and Map of Shanxi Province,this research acquired the digital geomorphologic type distribution characteristics of administrative units at multi-levels in Shanxi Province,by using GIS spatial analysis and numerical statistical analysis methods.The research results show：the area distribution percentages of the four geomorphologic types- plain,terrace,hill and mountain in Shanxi Province are 19.10%,15.77%,14.72% and 50.41%,respectively;In the 11cities of Shanxi Province,Shuozhou City mainly distributes plain geomorphology,Yuncheng City mainly distributes terrace geomorphology;Other cities all mainly distribute mountain geomorphology;In the108counties of Shanxi Province,19counties mainly distribute plain geomorphology,17counties terrace geomorphology,12counties hill geomorphology and 60counties mountain geomorphology.
