摘　　要：目前对采用水文干旱方法,即通过监视农田墒情的变化来建立抗旱决策信息系统研究还很少,文章阐述在干旱灌区建立土壤墒情监测预报和灌溉决策信息系统的重要性,提出适用于干旱灌区的土壤墒情监测方法和作物灌水预报模型,对土壤墒情自动测报及灌溉决策系统的信息传输、结构及功能作了详细论述。研究表明,通过计算机信息技术对农田墒情、气象信息、灌溉用水以及农业生产等综合信息实行一体化系统管理,提高了灌溉管理水平,节约了水资源。研究成果在干旱、半干旱地区具有参考和应用价值。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.
