Recently, with the implementation of continued and matching construction and water saving projects in large-sized I, information management level of water resources has been require much higher. However, the management of water resources quite lag, and traditional manual work can not share the efficient data information, which resulted in low management efficiency in ID. All these problems have constrained the sustainable development of ID more or less. Henceforth, it is critical to apply modern management method to utilize water resources. GIS, with the popular technique, is offering scientific and practical technology method for such demand.With the establishment of visual management information system of water resources in ID based on GIS, managers can not only master the overall condition of ID through graph and quick inquiry of non graph data, but also integrate, analyze, compute and manifest the discrete data, which increase the information acquisition remarkably and improve information quality and utilization degree.
