摘　　要：等值线图是众多学科成果展示的必要图件之一。针对传统的基于规则网格的等值线追踪算法的复杂性和不确定性,提出一种基于规则三角网的等值线追踪和等值线填充算法,并运用C++编程语言在VC++6.0集成开发环境中实现了该算法。最后将编制的软件应用于区域地球物理调查成果集成与方法技术研究项目中,并通过与surfer9软件在成图效果和成图速度的对比,证明了算法的正确性和高效性。The contour map is one of the necessary maps in the field of exhibition on the achievements.This paper presented a contour tracking and contour filling algorithm based rule triangular network for the complexity and uncertainty of the traditional algorithms,and the algorithm is implemented in the development environment VC++6.0.Finally,the accuracy and efficiency of the algorithm by contrast with surfer 9software is proved by the application of the software in the actual project.
