摘　　要：晕渲法是利用色彩和光影有规律的变换和组合来表示地表起伏变化的方法。基于ArcGIS平台,文章首先分析了光源方向(光照角)、光源入射角(高度角)和垂直比例因子的选择对黑白晕渲效果的影响,然后分析了基于黑白晕渲和分层设色的彩色晕渲图制作方法,对实践工作具有较强指导意义。The method of hill shading represents the change of surface fluctuation through regular combination of color and light. Based on the ArcGIS platform, firstly the paper analyzes the influence of light source direction （illumination angle）, light incident angle （elevation angle） and vertical scale factor on black and white shaded effect, and secondly describes the making methods of shading map based on black and white shaded relief and hypsometric color. It is very meaningful in practical work.
