By capturing and processes the metadata information on earth system science field data resources under China Scientific Data Sharing Project (SDSP), the statistic analysis on the metadata is conducted from different angles. The basic status quo of scientific data resources in earth system science field under SDSP is given. Then, the features of institutions for data collection, production, and publish as well as their geographical relations are focus on. The conclusion shows that scientific data sharing in this field has formed certain model involving data collection, production, and publish; regional distribution of data resources and relevant institutions has shaped a certain pattern. However, the quantity of shared scientific data resources in earth system science field is small, the management and sharing of scientific data is at its initial stage.
