摘　　要：为应用GIS技术建立成矿区带矿产资源评价的多源地学信息系统 ,本文对物化探信息按GIS技术上的要求 ,建立了科学、规范、实用的数据分层标准及数据记录格式。将物化探信息分成重力、航磁、化探、物探异常、化探异常等 5个大类 ,及 11个主题图层。制定了分层和命名规则。With the aim of developing GIS a multisource geoscience information system for estimating mineral resource in metallogenic provinces, a scientific, normal and practical criterion of data layer and data format were presented in the paper. The geophysical and geochemical information is classified as 5 categories (gravity, aerial magnetic anomaly, geochemical prospecting, geophysical prospecting anomaly and geochemical anomaly), and 11 theme layers Meanwhile, the coding rules of how to classify the data and layer and to name was presented. On the basis of this, the data format was given systematically.
