There are 9 regular member data centers in China under the umbrella of the International Council for Science-World Data System (ICSU-WDS). They are Chinese Astronomical Data Center, WDC-Renewable Resources and Environment, WDC – Oceanography at Tianjin, World Data Centre for Microorganisms, Chinese Space Science Data Center, Cold and Arid Regions Science Data Center at Lanzhou (CARD), WDC for Geophysics at Beijing, Global Change Research Data Publishing and Repository (GCdataPR), and Fish Database of Taiwan. The poster gives a whole picture of 8 data centers in China mainland, including the host agency, development history, main field, core data resources, special services and its domestic and international profile of each centers. Their main contributions for the international communities are summarized and highlighted. For example, Chinese Astronomical Data Center has become the members of International Virtual Observatory Alliance since 2002. There are more than 19000 users at present. WDC-Renewable Resources and Environment has organized several times of international young scientist training in the past few years. It also charged for the design and development of the WDS China Common Clearing House Prototype. WDC – Oceanography at Tianjin is responsible for the management of national marine data and information resources, and providing guidance and scientific stewardship for the national marine data and information. World Data Centre for Microorganisms is a vehicle for networking microbial resource centers of various types of microbes. It also serves as an information resource for the customers of the microbial resource centers. Chinese Space Science Data Center provides services for serials of space science plan, e.g. Space-based multiband astronomical Variable Object Monitor, Solar wind Magnetosphere Ionosphere Link Explorer, International Space Weather Meridian Circle Project, etc. Cold and Arid Regions Science Data Center at Lanzhou (CARD) has been the scientific data depositories of a serial of international academic journals, e.g., Science Report, PLOS ONE, etc. WDC for Geophysics at Beijing provides plenty of long-term, continuous geophysical observation data, such as the earliest ionospheric data in China since 1946, the earliest geomagnetic data in China since 1897, etc. It hosts the mirror sites of Madrigal Database and DIDBase. Global Change Research Data Publishing and Repository (GCdataPR) advocates an innovative data sharing approach which integrates metadata, data products and data papers together


The authors would like to express appreciations for support from WDS world data centers in China, National Science & Technology Infrastructure of China, and CODATA-China Committee.
