摘　　要：主要探讨基于GIS的重砂数据的自动化解译,建立重砂空间信息库的实现过程。对单矿物建立重砂地球化学图、异常图;对多矿物进行空间的组合异常分析,建立组合异常图。在建立各类图形库的同时,建立相应的空间信息合成属性库。实现从标准重砂数据输入到空间图形数据库、信息库自动建立的自动化解译建库手段,为重砂在地学各领域的充分应用,提供了一个有用的空间信息合成库。目前,该模块已在我国试运行,服务于矿产预测、资源与环境评价等领域。The conservation and space-distributing of schlich mineral are controlled by landform condition. The distributing-laws of schlich mineral will provide useful information in surveying distributions of protogene metallization. Thus, integrating schlich space information based on GIS, as a part of the system of Synthesis Information and Mineral Forecasting, is very important to veracity of metallogenic prognsis. This paper discusses the automatic interpretation of schlich data and the process of setting up space information-base of schlich. Maps of geochemistry and abnormality about single mineral of schlich have been established. An integrated anomaly map has been set up based on comprehensive analysis. All spatial information attribute-bases can be formed at the same time. The realization of input from standard schlich data to spatial map bases and automatic establishments of spatial bases will supply a quite useful integrating base about spatial information for fully application schlich into every field of geosciences. Now, the trail version of this program has used in mineral prognsis and the estimates of resources and environment in the country.
