应用人工智能中的专家系统技术，开发并集成了3个不同层次的节水灌溉管理决策支持系统：灌溉预报与节水灌溉决策子系统、灌区计划用水与水量调配管理系统、灌区管理体制改革子系统；介绍了节水灌溉管理智能决策支持系统的理论基础，系统结构，实际应用以及陕西省旱情决策子系统等。

By using the techniques of expert system of artificial intelligence, three different water saving irrigation management decision-making support systems have been developed and integrated, namely Irrigation forecast and decision making of water saving irrigation, planning water use and water distribution in an irrigation district, and management system reform in irrigation district. Meanwhile, the theoretic basis, systems structures and practica applications and the crop drought decision making in Shanxi Province are introduced. The research, development, spread and application of water saving irrigation management intelligent decision-making support system will promote the transfer of the traditional agriculture to modern one, and open a new way for sending the high and advanced agricultural technology to hundreds of millions of farmers.
