海洋可信数据空间建设进展及典型案例研究OA

As data elements become core strategic resources in the digital era,trusted circulation and efficient utilization of marine data have become key supports for the development of marine affairs.This paper systematically reviews the construction progress of marine trusted data spaces in the EU,the United States,Canada,analyzes China's practice cases such as China's Marine Cloud,China Global Ocean Fusion Dataset 1.0,Zhejiang,Qingdao,etc.,and takes Shenzhen as an example to analyze four core challenges China faces in releasing marine data elements:"dare not use,insufficient supply,difficult to use,and do not know how to use",and proposes a four-dimensional collaborative path for marine trusted data space construction involving"system-technology-channel-ecosystem".
