在当前数据经济时代，数据安全已成为国家安全战略。海洋科学数据安全是海洋数据资源管理与共享服务最紧迫的核心问题。本研究在充分分析海洋科学数据安全治理需求和目标基础上，提出以数据为中心的海洋科学数据安全治理体系框架，在此框架下提出海洋科学数据安全治理体系模型，并在国家海洋科学数据中心开展治理实践，优化了海洋科学数据全生命周期各阶段的安全管理，确保在数据安全的基础上，进一步提高了海洋科学数据开放力度，发挥海洋数据价值。

In the current era of data economy, data security has risen to the national security strategy. Marine scientific data security is the most urgent core problem of marine data resource management and sharing services. Based on the full analysis of the needs and goals of marine scientific data security governance, this paper proposes a data-centered marine scientific data security governance system framework, and proposes a marine scientific data security governance system model under this framework. The governance practice is carried out in the National Marine Science Data Center to optimize the security management of all stages of the whole life cycle of marine scientific data. On the basis of ensuring data security, the openness of marine scientific data is further improved to give full play to the value of marine data.
