With the increasing attention paid on facilities and projects of hydrology and water resources by the government, the planning and management of the network becomes more onerous. Based on the practical situation of Yangtze River basin network and combined with GIS technology, we discussed the design and realization of the network management platform through function module design, database design and main algorithm design. The system function modules include data organization and manage-ment, information query and display, aided planning and analysis, flood control decision and support, algorithm design and key technology of precipitation isosurface and areal rainfall calculation. The system can organize various stations orderly and access to the data quickly;meanwhile, the data and algorithm provides basis for the hydrological network planning and flood control deci-sion-making.
