　　Abstract: Scientific data sharing is of great significance for enhancing national scientific and technological innovation capabilities and promoting social and economic development. In order to improve the sharing ability of the Yangtze River hydrological data resources under the background of big data, the related concepts of hydrological data are proposed based on the study of hydrological data characteristics. At the same time, in combination with the open application requirements of hydrological data, this paper studies the construction of an open platform construction system with open applications of data and capabilities, and proposes the overall framework and functional structure of the open hydrological data platform. By analyzing the foundation and conditions of the hydrological data open platform for the construction of the Yangtze River hydrology, this paper designs the construction contents of the open platform, explains the challenges of platform construction in terms of data open scope, quality assurance, open friendliness and security, and puts forward countermeasures and suggestions from the aspects of open mechanism, product form, application ecology, etc., which could provide an important technical guarantee for the application of the platform.
