摘　　要：在矿床统计预测中，如何确定最佳的统计预测单元，目前尚无通用的准则和算法，它的划分往往取决于地质学家对研究区控矿条件的认识，矿化的实际分布形态及统计预测所采用的评价模型等多种因素。在系统总结和研究单元划分的领域专家知识的基础上，提出了用产生式规则语言来表达单元划分的知识结构和实现方式，探讨了用Ｃ语言设计和实现单元划分专家系统的方法和途径。系统功能齐全，基本上满足了资源评价的各种需求。In statistical prediction of mineral deposits,there have been no general criteria and formulae as to how to determine the most suitable unit.Its partition usually depends on geologists' recognition of ore controlling conditions,distribution shapes of mineralized occurrences as well as appraisal models used.Based on systematic summarization and research of field expert knowledge of unit partition,this paper suggests that knowledge structure and realization method with IF￣THEN rule language is used to express unit partition.It also discusses the methods and ways of using C programming language to design and realize the expert system for unit partition.The program system has perfect functions.These methods can satisfy various requirements of resources assessment,and realize automation and intellectualization of the prediction unit partition.
