摘　　要：【目的】地貌是地球表层系统最重要的自然地理要素,其形态划分对地学空间分异研究具有重要意义。【方法】以山西省西山矿区作为研究区,利用该区ALOS 12.5 m DEM数据,通过窗口递增分析和均值变点分析得到地形因子最佳分析窗口为13×13(0.0264 km^(2));利用相关性分析获得最佳地形因子为地形起伏度、海拔高度、坡度、地表切割深度和地表粗糙度;利用区域统计分析得到典型地形因子的分布状况,结合叠加分析提取了西山矿区30种地貌类型,其中浅切割陡小起伏中山为主要地貌,占总面积比为21.23%.【结果】通过与1∶100万地貌类型图的图斑数和地貌分类界线对比,得出地貌类型增加了21类,图斑数目增加了296个,分类界线更为准确,验证了研究结果具有一定可靠性和可行性。【结论】本地貌划分方法较以往更加科学可行,为进一步研究西山矿区灾害防治、开发利用等问题提供了数据参考。【Purposes】Geomorphology is the most important physical geographical element of the Earth's surface system,and its morphological division is of great significance to the study of geospatial differentiation.【Methods】Xishan mining area in Shanxi Province was taken as the research area,on the basis of the ALOS 12.5 m DEM data of the area,the optimum analysis window of the relief amplitude was determined to be 13×13(0.0264 km^(2))according to the window increment analysis and mean-variation analysis.The optimal terrain factors,such as relief amplitude,elevation,slope,surface incision,and surface roughness were obtained by correlation analysis.The distribution of typical terrain factors was obtained by regional statistical analysis,and combined with superposition analysis,30 geomorphic types were extracted in Xishan mining area,among which shallow cut steep and small undulating mountain was the main geomorphic,accounting for 21.23%of the total area.【Findings】By comparing with the number of map spots and geomorphic classification boundary of 1∶1000000 geomorphic type map,it was concluded that 21 geomorphic types and 296 map spots were added,and the classification boundary was more accurate,which verified the reliability and feasibility of the research results.【Conclusions】The landform classification method in this study is more scientific and feasible than before,which provids data reference for further study on disaster prevention,development,and utilization in Xishan mining area.
