摘要
现有的确定水型分区界线的方法缺少数学上的严密性、无法客观地确定水型的空间分布与转化关系，会使水化学图的编制工作遇到一系列难以排解的困难，也不利于实现图件编制的规范化。本文提出一种可以准确确定水型分区界线的作图方法，该方法可使作图的难度大为减少，并使图件反映的详细程度、精度程度大为提高。
A new method for drwing Chemical map of ground water was presented in this paper.The new mathod is based on the mathematical law instead of the old method that based on the individual experience.So,It can determining The positions of chermical classiffication Line very correctly and very effictively. \ \
