Abstract: The importance of establishing the automatic telemetering system for soil moisture and irrigation decision-making information system in the arid irrigation areas was stated in detail in this paper. However, there is little research on establishing the drought-resistance decision-making information system through the method for hydrological drought-monitoring of the change of soil moisture in the farmland so far. It also introduces the method for monitoring soil moisture and the forecasting model for irrigation in arid irrigation areas. Moreover, the paper specially states the way of information transferring, structure and function of the automatic telemetering system and irrigation decision-making system for soil moisture. Research results indicated that the integrated management system for the comprehensive information including soil moisture, meteorological information, irrigation, agricultural activities, can be applied through the information technology. As a result, the application of the system improved the level of irrigation management and water resources use. Much useful implication can be abstracted from the research for water resource management in the arid and semi-arid areas.
