摘　　要：以GIS为主要技术平台,基于山西省数字高程模型,采用窗口分析法提取了山西省地形起伏度,并分析了山西省地形起伏度的分布规律及其与人口分布的相关性.研究表明:山西省地形起伏度以低值为主,呈现出东北高—西南低的空间分布格局;山西省地形起伏度经度变化规律呈N字型变化即随着经度的增加,表现出"升高—降低—升高"的趋势;随着纬度的增加,地形起伏度呈现逐渐升高的趋势;山西省地形起伏度对人口分布有较强的影响.Based on the digital elevation model of Shanxi and GIS as the main technology platform,the relief degree of land surface（ RDLS） in Shanxi was extracted by the method of window analysis,and the distribution rule of the RDLS and the correlation between the RDLS distribution and population distribution are analyzed.The results show that the RDLS is dominated by low value,showing the spatial distribution pattern of the northeast high-southwest low. The change regulation of RDLS was N shape,namely,with the increase of longitude,showing a ＂increase-decrease-rise＂trend. With increasing latitude,RDLS presents a rising trend and RDLS has a strong influence for population distribution in Shanxi.
