Abstract: Irrigation real-time operation is an important mark of agriculture water management heading for intelligent,automation and modernization.Its future lies in synthesizing geographical information system,satellite remote sensing,global position system,computer,artificial intelligence,information technical,and agriculture irrigation,meteorology,system engineering,and improving the flexibility,reliability,and adaptability of irrigation operating.Meanwhile,it is faced with more difficulties such as the basic facilities backward,technical resources weak,and information process expensive,satellite transmission period longer,and so on.In order to promote development of irrigation water management research,this paper reviews the important advances and latest achievements in the research of real-time irrigation forecast,channel water dynamic allocation,field moisture monitor,computer assist decision support system and irrigation space information management.
