This paper discusses the necessity of construction of a water information data sharing system in China and identifies the difficulties and challenges for construction of the data sharing platform by analyzing the practice of Chinas water resources informatization. The main problems are decentralization of the early information management, the narrow scope of various water information departments, and ununified storage standards. On this basis, the future direction for construction of Chinas water information sharing system is proposed. The premise if overall planning of such resources as infrastructures and water resources applications based on integration of basic resources. A unified data storage standard and data security are key factors and foundations to guarantee a successful and well-operated data sharing system.
