摘　　要：数字矿床模型(DDM)是传统矿床模型的数字化。本文论述了数字矿床模型的概念,提出了其主要组成结构和建模关键技术。在吸收国内外地质领域专家系统建立的经验基础上,将人工智能技术与地理信息技术(WebGIS)相结合,通过构建矿床模型知识库,建立数字矿床模型推理网络结构,并以斑岩型铜矿为例论述了建立数字矿床模型的系统过程。本文是"十一五"期间国家高技术研究发展(863)计划的阶段成果。Traditional mineral deposit models usually provide a qualitative description of geological properties, tonnage, scale and genesis of a group of similar types of mineral deposits. These types of qualitative models provide guidelines for establishment of the digital mineral deposit model which has been considered to be a new research area. This paper deals with the concept of the digital mineral deposit model as well as the construction of the Digital Mineral Deposit Model including reasoning network and knowledgebase. The model and system were verified through a case study of porphyry copper deposits in China. The results presented in this paper reflect the preliminary achievements of a project supported by Chinese High-Technology Research and Development （863） Program.
