摘要: GIS作为一种先进技术, 在矿产资源勘查与评价中得到广泛应用.以MapInfo为平台、MapBasic为二次开发工具, 利用多源地学信息建立了矿产资源综合评价系统.该系统对Map-Info的功能进行了扩充, 建立了新疆东天山地区航空物探数据库, 增加了空间分析和矿产预测功能, 对新疆东天山某地区蚀变岩型金矿进行了综合评价.研究结果表明, 将传统的解释方法与数理统计方法及地理信息系统技术相结合, 是综合多源地学信息进行矿产资源预测的有效途径.

Abstract: GIS is an advanced technology and is widely applied in the exploration and assessment of mineral resources. With MapInfo platform and MapBasic program, Mineral Resources Assessment System has been developed by using multiparameter geological information, in which MapInfo functions are expanded and spatial analysis and metallogenic prognosis methods are added. With this method aero geophysical database in the eastern Tianshan region of Xinjiang is established and the alteration gold deposits in this area are assessed comprehensively. Study results show that it is the effective way for metallogenic prognosis that traditional explanation method is combined with mathematical statistics and GIS.
