Studies On Using GIS Module To Develop Irrigation Information System

The 21st is the century of water. Because of the development of modern economic and the increasing of world population, there will be lack of water severity in the future. So the best way of using water will play an important role in agriculture. Water management by information is one of best way to use water. It protests using modern communication technology, geographic information system and multimedia edit in the water management in order to enhance the efficiency of water management in the future.The paper ascertains the research of application modern communication technology, geographic information system and multimedia edit in the management of water in the new century. Based on survey the need of work in irrigation districts and reference research methods or tools in domestic and foreign, the paper works out the structure and function of IMS, with MapX being development tool. IMS enhances the efficiency of water management in irrigation districts, thus it has important role for the development of the irrigation districts and the increasing of national economy.IMS composes eight function modules: general situation of irrigation districts, database management, network communication, visual information query, report output, dynamic simulation, help, exit. The object oriented program, geographic information system, multimedia edit and the method of water management are use to turn function modules into reality on the computer, with visual programming language-visual Basic6.0 and Mapinfo corporation's ActiveX-MapX being development environment. After inspecting and practicing system time after time, IMS has rapid response, simple manipulation, easy to use, practical, advanced and transplantable.
