矿产资源的自然属性、经济属性和社会属性，决定了矿产资源安全涉及众多资源类型、宏大空间分布、超长产业链条、巨大产业规模、跨越时空配置、复杂因素影响、层次纷繁多样。矿产资源安全规模之大、层次之多、影响因素之复杂难以穷尽，是一个复杂巨系统。如何使矿产资源安全巨系统高效运转以服务经济社会发展，是一项复杂性科学难题。本文引入系统科学的研究思路，提出了矿产资源安全巨系统概念，刻画了矿产资源安全巨系统的结构和组成，揭示了自然资源、经济、社会等因素对矿产资源安全巨系统的驱动机理，形成了矿产资源安全巨系统理论。在此基础上，建立了涵盖以系统思维研究构建矿产资源安全保障的理论知识模型、构建基于大数据平台的仿真实验系统、积极推动政府决策与反馈三大环节的矿产资源安全系统工程学研究新方向，提出了建立矿产资源安全的总体设计部的战略思想。研究成果已应用于国家资源安全保障工作实践，有效支撑了国家矿产资源安全保障工作。

The natural, economic, and social attributes of mineral resources determine that the security of mineral resources involves numerous resource types, large spatial distribution, ultra-long industrial chains, huge industrial scale, spatial and temporal configurations, complex factors, and multiple levels; it is a complex and giant system with a large scale, multiple levels, and complex influencing factors. How to make this system operate efficiently and serve economic and social development is a complex scientific issue. This study puts forward a concept of giant system for mineral resource security by introducing the research idea of system science, depicts the structure and composition of the giant system, and reveals the driving mechanism of the giant system by natural resource, economic, social, and other factors. On this basis, a new research direction of system engineering of mineral resource security is established, which involves building a theoretical knowledge model for mineral resource security guarantee using a system thinking, constructing a simulation experiment system based on a big data platform, and actively promoting government decision-making and feedback. Furthermore, a major strategic idea of establishing an overall design department for mineral resource security is proposed. The research results have been applied to and effectively supported national resource security guarantee in China.
