摘　　要：专题地图是展示物探研究成果最为直观的表现形式之一,而一张成果图的定稿需经多次的修改完善。根据地质解释图的制图特点和要求,以电磁法中的断面解释图为例,利用Python语言中丰富的第三方库,设计编写了自动化制图程序。文中对不整合线(波浪线)的绘制、微短线删除、多边形化、颜色填充等主要环节进行较为详尽的阐述,并提供了关键代码。The thematic map is one of the most intuitionistic forms for presenting the research results in geophysical exploration.Nevertheless,a final result map needs to be revised and improved many times.According to the characteristics and requirements of geological interpretation map and with a section map of interpretation by electromagnetic method as an example,the authors designed and compiled an automatic drawing program by using Python language and its rich third-party libraries.In this paper,main links,such as drawing unconformity line(wave line),deleting micro-short line,polygonization and color filling are described in detail.Meanwhile,the key code are provided.
