摘　　要：用计算机绘制大气污染物长期平均浓度分布等值线图,对在绘图过程中坐标系的建立、计算网格间距的确定以及风向的加密等的处理方法作了讨论,并给出了绘图的基本步骤。A general procedure for drawing concentration contour graph of air pollutants using computer was presented. On the basis of detailed discussion, several technical notes were reconmmended to solve the key issues in the procedure, such as establishment and conversion of coordinate system, determination of interval of calculation grid and interpolation of wind direction. Finally, the basic steps of the method were summarized.
