摘　　要：本文通过对曾广鸿等人[1]提出的利用三次Bezier曲线拼接模型实现满足拓扑关系的折线式等值线曲线化的理论方法进行编程实践后,发现仅仅根据文中的方法不能完全正确地实现等值线的绘制,为此作者通过编程实践对该方法进行了补充与完善,文中详细完整地介绍了能完全满足拓扑关系的折线式等值线全参数曲线化的具体实现方法。After realization by programming to the theory of Curve-rization to Broken-lined Contours with Topotaxy Utilizing Triple Bezier Curve Jointing Model proposed by Zeng Guang-hong et al. , we found that contours can＇ t be drawn absolutely correct depend on this method only. For the purpose, complement and improvement were carried out in this article. Concrete realization method of the all-parameter curve-rization to broken-lined contours with complete topotaxy was introduced completely in detail.
