Abstract：Water conservancy involves a lot of business, the frequency of data generated by these businesses is different, and the requirements of timeliness are also different.In order to solve the contradiction between the timeliness of data sharing and resource occupancy rate,a hierarchical and efficient data sharing mode of water conservancy is proposed. Based on the requirements of data update frequency and sharing timeliness, the data of water conservancy is divided into four categories:high frequency high time efficiency, low frequency high time efficiency, high frequency low time efficiency and low frequency low time efficiency. Combined with the characteristics of different sharing modes, the hierarchical sharing mode of polling-broadcast-subscription and the security guarantee mechanism of authorization-authentication-encryption are designed and applied in Guangdong Province. The results show that the hierarchical and efficient sharing mode of water conservancy data can effectively improve the timeliness of data sharing and reduce the occupancy rate of network, server and other resources, and realize the efficient sharing of multi-source heterogeneous data.
