摘　　要：等值线图的颜色划分直接影响着物探成果的认知与判断。文章根据不同工区大量物探数据成果,针对不同物探方法的等值线数据分布特征,总结了基于经验划分数据的不足之处,提出两种简易划分数据的方法。同时为改善等值线图的配色效果,遵循感知色彩的均匀性和和谐性原则,通过对RGB颜色空间的介绍,明确各颜色的数值含义,重点解释色彩的感知距离,科学建立不同色彩和划分数据之间的映射关系。在数据划分和颜色设计的基础上,通过实例验证新色阶在颜色选取及突出局部等方面的优势。The color distribution of the contour diagram directly affects the cognition and judgment of geophysical results.Based on the results of a large amount of geophysical data in different work-areas,this paper summarizes the shortcomings of dividing data based on experience according to the distribution characteristics of contour data in different geophysical methods,and proposes two simple methods for dividing data.At the same time,in order to improve the color matching effect of the contour diagram,it follows the principle of uniformity and harmony in color perception.Through the introduction of RGB color space,it clarifies the numerical meaning of each color,and focuses on explaining the perceived distance of color.The mapping relationship between different colors and data division is scientifically established.On the basis of data division and color design,the advantages of the new color gradation in color selection and highlighting local details are verified by examples.
