面对新技术环境的变革和图书馆数据化的变迁，图书馆现有的数字资源保存系统在基础理论、工作流程、技术体系等方面受到巨大冲击。在图书馆数据化转型的关键时期，有必要增强长期保存系统的并行处理和灵活扩展能力，解决面向大数据集的集中保存和利用问题，满足海量数据的摄入、存储、管理和服务需求。文章从保存对象数据化态势的形成出发，从不同维度分析保存系统需求的变化，在分析现有保存系统亟待改进的问题的基础上，提出数据化视角下图书馆数字资源长期保存系统平台模型，以期为我国图书馆长期保存系统理论和实践的发展提供借鉴。

Facing the change of new technology environment and transition of library digitization, the existing preservation system of library digital resources has been greatly impacted in the aspects of basic theory, workflow, technical system, etc. In the critical period of the library digitization transformation, it is necessary to enhance the parallel processing and flexible expansion ability of long-term preservation system, solve the problem of centralized preservation and utilization of big data sets, and meet the requirements of intake, preservation, management and service of massive data. Starting from the formation of the digitization situation of preservation objects, this paper analyzes the changes of preservation system requirements from different dimensions, and on the basis of analyzing the problems to be improved of the existing preservation system, it puts forward the library digital resources long-term preservation system platform model from the perspective of digitization, so as to provide reference for the development of the theory and practice of library long-term preservation system in China.
