随着水资源的日益紧缺，非常规水资源的开发利用越来越受到各国的重视。利用非常规水资源进行灌溉是应对水资源紧缺的重要举措之一。非常规水资源农业利用以再生水和微咸水为主。中国农业非常规水资源具有较高的潜力，预计到2030年，农业可利用非常规水资源量为3.438×10¹⁰ m3，其中再生水和微咸水农田灌溉量分别为1.645×10¹⁰ m3 和2.48×10⁹ m3。在淡水资源紧缺、非常规水资源相对丰富的地区，充分利用非常规水资源是缓解淡水资源危机的重要途径。本文在介绍了中国非常规水资源农业利用现状的基础上，总结了非常规水资源的灌溉模式，从灌溉区划技术、适宜作物分类、污染识别技术、高效灌水技术、监测评价技术和集成应用模式六方面提出了非常规水资源安全灌溉保障措施，提出了加强农业非常规水资源灌溉技术研究与推广、完善农业非常规水资源回用的标准规范体系、将非常规水资源纳入水资源配置与开发利用规划以及制定农业非常规水资源开发利用激励政策的发展策略，以建立适合我国气候特点和国情的农业非常规水资源利用技术体系。

With the increasing shortage of water resources, the development and utilization of unconventional water resources have received more and more attention from various countries. Using unconventional water resources to irrigate is one of the important measures to deal with the shortage of water resources. Unconventional water resources mainly include the reclaimed water and brackish water. In China, the agricultural unconventional water resources have relatively high potentials. It has been predicted that the amount of unconventional water available for agriculture will reach 3.438×10¹⁰ m3 in 2030 and the irrigation amount of reclaimed water and brackish water will be 1.645×10¹⁰ m3 and 2.48×10⁹ m3, respectively. In areas where the fresh water resources are lacking and the unconventional water resources are relatively abundant, especially in the arid area in the north, developing and using unconventional water resources can be regarded as a good solution for the shortage of fresh water. In this paper, based on the situation of China, the irrigation mode of unconventional water resources was summarized. From the aspects of zoning technology, suitable crop classification, pollution identification technology, high-efficient irrigation technique, monitoring and evaluation technology, and integrated application mode, this paper proposes the safe irrigation measures of unconventional water resources in China. Finally, in order to establish a technical system of agricultural unconventional water resources utilization suitable for China, this paper puts forward the development and utilization strategy, which is to further strengthen the technical research and popularization of the agricultural unconventional water resource utilization technology, to improve the recycling standards and regulation system, to bring the unconventional water resources into the planning of water resources development and utilization, and to formulate incentive policies.
