摘　　要：目的以区域成矿理论和空间信息科学思想为指导,以对象-关系型GIS为技术支持,构建基于信息科学思想的资源潜力评价体系。方法遵循"一致性原则"和"分层次进行原则",构建资源潜力评价体系,将资源潜力评价体系分为"可能成矿区域划分及资源潜力计算"和"在可能成矿区域内进行远景区(靶区)圈定"两部分内容。"两个原则"和"两部分内容"构成完整的资源潜力评价体系。结果所提出的资源潜力评价体系实现了从"制图学"思想向"信息科学思想"的转换,转换的关键是将"矿床模型"作为"空间数据模型"和"空间数据分析模型"的唯一依据,从而实现"成矿理论"和"信息技术"间的整合。结论基于信息科学思想的资源潜力评价体系保证了"矿床模型-资源潜力评价数据模型-资源潜力评价空间数据库-资源潜力评价空间分析方法-资源潜力评价结果"的连续性和一致性,使整个评价体系满足简单、高效要求。Aim Taking regional metallogeny and spatial information science as guideline,supported by GIS of object-relation Model,to construct a information science based methodology of Mineral Resource Assessment（ MRA）. Methods Following ＂Consistency Principle＂ and ＂Hierarchally processing Principle＂,a information science based methodology of MRA is conceived. The two parts of ＂delineating the permissive tract for undiscovered mineral deposits and assessing mineral potential＂ and ＂Finding out the target of mineral potential in the permissive tract＂ are its main content. The ＂two principles＂ and ＂ two parts＂ constitute whole content of the methodology. Results The methodology realized the transformation from cartographic MRA to information science based MRA. The key point of transformation is to construct spatial data model and spatial data analysis model only based on mineral deposit model. In this way,the integration of ＂Regional Metallogeny＂ and ＂ Modern information technology＂ can be achieved. Conclusion The information science based methodology of MRA guarantees the continuity and consistency of mineral deposit model,spatial data model,geodatabase,spatial data analysis and the results of MRA. It is also simple and effective comparing with cartographic MRA.
