摘　　要：提出了一种通过明暗等深线结合分层设色的途径,在二维平面图上实现海底地貌形态三维立体表示的方法。对等深线明暗特性与分层设色方案确定的方法进行了深入的研究,建立了相应的数学模型,并给出了实例,对该方法的有效性进行了验证。In this paper, a method of combining illuminated depth contour with color gradients was advanced, which realized the purpose of showing three-dimensional sea floor on two-dimensional chart. The means of deciding illuminated depth contour and color gradients were studied and corresponding model was established. Then the validity of this method was tested by experimentation.
