区域地质调查是一项综合性的基础地质工作，它几乎涉及地质学领域的各个方面，其９０％以上的数据与空间位置有密切关系。因此，ＧＩＳ在区调工作中有着广阔的应用前景。针对区调工作的特点和需要，阐述了应用ＧＩＳ时必须解决的问题，包括硬件的配备、软件的选择、人才的培养和标准化。重点论述了ＧＩＳ在建立全国地质图图库、区调填图和全国区调管理中的应用前景及其重要意义 Regional geological survey is a comprehensive basic geological work, it covers almost all aspects of the field of geology, more than 90% of the data are closely related to the location of the space. Therefore, GIS has a broad application prospect in the area adjustment work. In view of the characteristics and needs of the district transfer work, the problems that must be solved when applying the GIS are expounded, including hardware equipment, software selection, personnel training and standardization. The application foreground and its significance of GIS in the establishment of the national geological map library, district transfer map and national district transfer management are mainly discussed
