区域地质图图例系统库调用方法与应用研究

为合理解决MapGIS系统库与国家标准之间的有效衔接，提高实际应用效率，以《区域地质图图例》国家标准为基础，从规范的研究现状、系统库的调用方法以及实际应用等3个方面，介绍了如何将现行标准、系统库与应用系统紧密结合，重点解决了三者之间的应用衔接问题。研究成果不仅对于优化系统库的应用方式及提高系统库的应用效率具有实际意义，而且对于地理信息系统的升级完善和系统库的补充完善均具有重要指导意义。

Method Call and Application Research on System Library of Regional Geological Map Legend

In order to solve effective connection between the library and the national standard for the MapGIS system for reasonable，improve the efficiency of practical application，based on the regional geological map illustration national standards，we introduced how to combine closely with the current standard，system libraries and application system from three aspects of the research status of specification，system libraries method call and practical application，finally the paper solved the problems of connection among them in the application.Overall，the results had practical significance not only for optimizing the application of system libraries and improving the efficiency of the application of the system library，but for the geographic information system upgrade complete，additionally it has important guiding significance for complementing system library.
