摘　　要：简要介绍了GR-660车载伽玛能谱测量系统的显著特点、全能谱信息挖掘的内涵和GIS技术在数据管理和信息提取中的应用。在铀资源勘查中,研究了放射性弱信息形成理论,并对全谱数据的应用进行了探讨。为了更好地从全能谱数据中获取丰富的地质信息,采用了噪声调整奇异值分解、空间相关性分析、铀富集系数、变异系数、多源信息的复合分析等信息挖掘方法。在沙麦盆地和白音呼布尔盆地铀资源评价中,对以上信息挖掘方法进行了应用试验,取得了较好的应用效果。GR-660全能谱测量系统还可以很好地用于辐射环境监测以及核应急事故调查。The paper briefly introduces the prominent characters of GR-660 Car-borne　γ　energy spectrum measurement system , the meaning of whole energy spectrum information mining and GIS technique application in the field of data management and information extraction. In the survey of uranium resources, the mechanism of weak radioactivity information is studied and the application of whole spectrum data is also discussed. In order to obtain more abundant geological information from whole spectrum data, several information mining methods are adopted, such as noise adjusted singular value decomposition, analysis of spatial correlation, enrichment coefficient of uranium migration and variation coefficient and integrgation analysis of multi-resource information etc.. In the processes of uranium resources evaluation in Shamai and Baiyinhubuer basins, the above information mining methods are applicated and improved results are obtained.
