摘　　要：从近 2 0年地质填图中计算机野外数据采集技术研究的现状和存在的问题入手 ,在确定地质填图空间数据表达的基础上 ,遵循传统地质填图的规律 ,在不约束地质学家地质思维的前提下 ,既能满足计算机处理的需要 ,又能保证地质工作者取全、取准各项地质观测数据 ,在描述各类地质信息空间关系的基础上 ,创建了数字地质填图过程标准化和规范化的PRB数字填图技术 ,并对构成PRB数字填图技术、PRB数据模型、PRB基本过程、PRB基本过程组合的规则、PRB过程的公共机制、PRB过程基本程式、PRB数据操作、PRB字典、三级PRB体系、PRB数据流“栈”、PRB数据质量定量评价体系的PRB数字填图技术与方法体系进行了讨论 .基于该项技术开发的数字填图系统和集GPS一体化的野外数据采集设备已在野外填图中推广应用 ,实践效果很好 .本文是在实践的基础上 ,通过对已有研究资料的进一步分析、总结而完成的 .To deal with the problems and present situation of field data capture by computer in geological mapping in 20 years, this paper has created PRB digital mapping techniques to standardize the digital mapping process and discussed PRB mapping technique-method system, including PRB digital mapping techniques, the model of PRB data and the related process, combinational regulations of PRB process, common mechanism and basic procedure of PRB process, data processing and dictionary of PRB, three-class PRB system, data flow stack and quantitative evaluation of PRB data. PRB digital techniques, based on establishing the expression of spatial data in mapping, complying with regulations of traditional mapping, and describing the spatial relationships among different kinds of geological information, will not only meet needs of computer operation, but also ensure geologists to collect geological observational data comprehensively and accurately. Meanwhile, they also satisfy the thoughts of geologists.
