[目的/意义]科技创新是我国发展的关键途径，需要科技资源的共享和协同创新。科技资源共享是一个系统工程，需要建立科技资源的描述模型，在此基础上进行科技资源集成、评价和分享。[方法/过程]提出科技资源描述模型的结构框架，包括：科技资源分类模型、科技资源元数据模型、科技资源本体模型、科技资源知识元模型、科技资源图谱模型等。其中，科技资源包括知识、数据、产品、人才、软件、硬件等资源。本文阐述了科技资源描述模型的特点和作用，并给出科技资源描述模型的建立方法。[结果/结论]本文的主要贡献是：①通过科技资源描述模型的规范化，有助于不同类型的科技资源的集成分享；②通过科技资源的不同类型的描述模型的集成研究，形成科技资源描述模型的体系架构，为进行科技资源的全面系统描述提供整体解决方案，有助于解决科技资源共享难的问题；③提出科技资源描述模型的建立方法，其特点是利用新一代信息技术依靠大众共建模型，依靠科技资源描述过程的大数据智能分析技术，建立和优化科技资源描述模型。

[Purpose/significance] Scientific and technological innovation is the key point of development, and scientific and technological resources sharing and collaborative innovation are indispensable. Sharing of scientific and technological resources is a systematic project, and first of all, in order to integrate, evaluate and share scientific and technological resources, we need to establish a description model of scientific and technological resources. [Method/process] The description model of science and technology resources defined in this paper includes classification model of scientific and technological resources, meta data model of science and technology resources, ontology model of science and technology resources, knowledge meta model of science and technology resources, science and technology resource graph model, etc. Scientific and technological resources include knowledge, data, products, talents, software, hardware and other resources. We proposed the method of establishing the model of science and technology resources description, as well as the characteristic and function of it. [Result/conclusion] The main contributions of this paper are as follows： standardizing the description model of science and technology resources is helpful for the integration and sharing of different types of science and technology resources; by the integration research of different types of description models of science and technology resources, we form the system architecture of the description model of science and technology resources, which provides an overall solution for the comprehensive and systematic description of science and technology resources, and helps us to share the science and technology resources ；we put forward a method to build a description model of science and technology resources, based on crowd-sourcing theory and big data AI of description process of scientific and technological resources, and we establish and optimize the description model of science and technology resources.
