STUDY ON WATER-SAVING IRRIGATION MANAGEMENT AND DECISION SUPPORT SYSTEM
On basis of the complexity and real-timeliness of water use management in farmland irrigation, the software of water-saving irrigation management and decision support system was developed.Based on the collected information including weather, soil moisture, crops, water resources situation, etc., crop water requirement was calculated by using the method of crop coefficient. According to the decision-making models of soil moisture, the irrigation prediction could be made to determine the accurate irrigation date and optimum irrigation amount by the system.Meanwhile, the irrigation equipments were automatically controlled and monitored to realize the aim of high-efficiency and water saving through the decision-making results. The system not only had the functions of inputting, editing, querying, statistics, outputting, etc., but also could provide the decision support of irrigation optimization and water resources optimal allocation for irrigation management departments and water users, as well as could make the precision irrigation schemes.It could provide with the functions such as the consultation of water-saving irrigation mode, the selection of the optimum irrigation schemes, and guiding optimum irrigation for users in irrigation districts, and it had the higher value in its application and popularization.
