摘要区域地质调查对于国民经济建设的各个领域的基础性、公益性地质工作素来都有十分重要的意义。
而在现代信息技术和空间技术高速发展的今天，区域地质调查工作过程的数字化已经成为一种必然趋势，它能够更好地实现信息共享和数据的更新，为地质工作服务。
我国的数字地质填图工作已经推广开来并稳步发展，但仍存在一些不足，这些不足之处影响了填图工作的准确度和速度，不利于数字地质填图的进一步发展。
本文通过总结四川省名山等4幅1:5万区域地质调查项目的经验，结合数字地质填图的工作方法，综合研究了该项工作从野外数据采集到室内数据资料整理、再到最后1：5万地质数据库的建立这3部分中容易遇到的问题，讨论这些问题出现的原因，并提出解决办法。
通过研究，本文肯定了数字地质填图方法相较于传统区调填图方法的优势，但并不表明数字地质填图方法就没有缺陷。
文中列举出了投影转换、野外数据采集、生成剖面图、柱状图等问题，这些问题一方面反映出数字地质填图硬件和软件方面的不足，另一方面对这些问题的讨论可供填图工作人员作为参考。
希望在今后的数字地质填图过程中，大家能少走弯路，更好更快地进行填图，为以后数字地质填图工作的顺利开展提供支持。

In the rapid development of the modern information technology and space technology today, The process of digitization of regional geological survey has become an inevitable trend, it can achieve better information sharing and data updates, for geological work.Digital geological mapping has promoted the development of open and steady in our country, but still there are some inadequacies, these deficiencies affect the accuracy and speed of our mapping work, is not conducive to the digital geological mapping of the further development. In this paper, such as by summing up the projects of 1:50000 regional geological survey in MingShan town of Sichuan Province, combined with the working methods of digital geological mapping, a comprehensive study on problems of the three parts of work from the field data collection, collation of data to indoor and then to establish the database of final 1: 50,000 Geological map. to Discuss the reasons for these problems and propose solutions.Through research, this article affirms the method of digital geological mapping in comparison to traditional methods of regional geological mapping of the advantages, but does not mean that the digital geological mapping method is not defective. The article cited a projection conversion, field data collection, generate profiles and histograms and other issues. On the one hand, reflects the hardware and softwareAbstractlimitations of digital geological mapping, on the other hand, the discussion of these issues to the future work of the digital geological mapping as a reference. I hope in the future the digital geological mapping process, we can less detours, better and faster to carry out the future work of digital geological mapping to support the smooth.Key words:Digital geological mapping PRB system defect Mapping accuracy Solution独创性声明本人声明所呈交的学位论文是本人在导师指导下进行的研究工作及取得的研究成果。
