【Abstract】 The Bohai Sea is one of the sea areas with the most prominent environmental problems in my country’s coastal waters. In recent years, in order to improve the environmental problems of the Bohai Sea, the authers has established a relatively complete environmental monitoring network and calculation model in the Bohai Rim region, and accumulated a wealth of land and sea ecological environment monitoring, survey, statistics and calculation data. However, there are huge challenges in the effective organization and management of eco-environmental data across time and space, multi-scale and multi-factor. In view of the urgent needs of the big data management of the ecological environment of the Bohai Sea, We constructs a progressive data management mode based on the original database, the original collection database, the standard database and the functional database. The multi-level database retrieval function provides a strong theoretical and practical basis for the development and improvement of the management and mining of massive multi-modal ecological environment data.更多还原
