Gis-based Yunnan Province, Water Conservancy, Hydropower Resources Management Information System

Along with national economy rapid development and social informationization degree fast promotion, All the various trades and occupations depend upon the information system more and more, There are many profession data' s application all to involve the spatial information. Thus the geographic information system (GIS)' s application is more and more widespread. The geographic information system has provided the powerful information processing and the policy-making support service for all the various trades and occupations.In order to understand and analyze the Yunnan Province water conservation and hydroelectricity resources further, Simultaneously also must carry on the management to its corresponding data. Thus needs to establish an information system, Because involves to the very many geography data, Therefore establishes based on the geographic information system Yunnan Province water conservation and hydroelectricity information system is must. Uses in managing the dispersible water conservation and hydroelectricity information resource, Enhances the water conservation and hydroelectricity information the management level. The increase decision-making scientific nature has the significant significance. This article main research content is as follows:(1) Union "Yunnan Province water conservation and hydroelectricity resources information management system" design and development, Detailed introduction geographic information system concept, classification, characteristic, application and prospects for development. And carries on the elaboration to this system introduction geographic information system.(2) At the beginning of system function design, Elaborated the information system design demand analysis from the software technology angle, Including graph data demand,property data,Statistical data demand and foundation application demand. In system project design process, Elaborated the system design thought,Principle of design as well as overall system design,Database design and system function design.(3) The application of the MapObjects component , Unifies Visual C++ to carry on integrates the re-development. Develop based on the geographic information system Yunnan Province water conservation and hydroelectricity information system, Realization system chart level operation,multiple queries,spatial analyse,export of report function and so on.Water conservation and hydroelectricity resources information management system research and development, Regarding raises the office automation level to have the very good function, have the effective enhancement production efficiency, Reduced time and resources waste, Have the very big help regarding the research and the decision-making.
