摘要
矿产资源评价是目前地质矿产勘查的重要任务，而地理信息系统（ＧＩＳ） 技术作为对多源地学信息进行集成管理、综合分析的有力工具， 越来越受到人们的重视， 并广泛地应用于矿产资源评价中。辽宁省ＧＩＳ矿产资源评价工作着重于建立基础数据库。目前，已建成物探、化探、地层、岩石地球化学、大中型矿产地等数据库。
The evaluation of mineral resources is an important work in the geological and mineral resoureces exploration at present. GIStechnich is a powerful means to centrally manage and com prehensively analyse geoscientic information of multiple source , which is paid more and more atten tion now and widely used in the evaluation of mineral resources. The centre of the GIS mineral resoures evaluation work in Liaoning province is the establishment of basic data bases. So far,the geophysical exploration ,geochemical exploration ,strata,lithogeochemical,large and middle scale mineral occurrences data bases of Liaoning province have been established .
