| 摘 要： | 文章论述了信息熵的概念、熵函数及其在地质成矿预测中的应用,其中着重论述了熵的几个重要性质与地质体状态的对应关系,同时介绍了在GIS(地理信息系统)平台上研究地质体信息熵异常的步骤,最后在甘南西部地区地学空间数据库建立的基础上,利用熵函数公式,计算出地质体的信息熵异常,并将该区的地质体信息熵异常作为一个信息图层,再结合研究区的物探、化探、遥感信息,对该区金矿进行了预测,圈出了金成矿远景区.

| Abstract: | the concept and function of information entropy, and its application in geological metallogenesis prognosis have been introduced. Several characters of entropy and correspondence to geological bodies are emphatically pointed out, and steps to obtain information entropy abnormity in studying region on the GIS platform are simultaneously introduced. Finally, based on the geological spatial database and using entropy function, the values of information entropy are calculated. Taking abnormity of information entropy as an information layer and combined with geophysical, geochemistry and remote sensing information, gold prospecting objective area in west region of southern Gansu province is predicted. |
