Abstract: Institute of Karst Geology of Chinese Academy of Geological Sciences currently has 6 field scientific observation and research stations, the earliest of which is built in 1986.These field scientific observation and research stations have accumulated a large number of long-term field observation data and test data, and the data resources are very rich, but there are some problems such as decentralized management and delayed sharing of data resources.In addition, some stations have problems such as data interruption due to lack of maintenance.Therefore, this paper proposes to build a data center of karst field scientific observation to achieve real-time convergence, scientific management, integration and sharing of data, improve the management and sharing service level of scientific observation and research stations, and give play to the value of scientific observation data.
