摘　　要：微咸水资源具有巨大开发利用潜力,利用微咸水资源代替部分淡水进行农田灌溉已经成为缓解水资源危机的重要途径,然而微咸水农田灌溉带来的安全问题始终是研究的重点和难点。分析了微咸水安全灌溉的影响因素,通过总结前人的研究成果,从灌水方式和灌水方法两个方面对微咸水安全灌溉模式进行了概述。然后,结合水盐监测和数值模型综述了基于微咸水水质标准的精准安全灌溉研究,阐述了解决微咸水灌溉下土壤安全问题的农田调控措施,总结了未来微咸水安全灌溉研究的趋势,为促进微咸水资源安全高效利用和农田安全灌溉提供参考。Brackish water resources have great potential for development and utilization.Using brackish water resources to replace part of fresh water for farmland irrigation has become an important way to alleviate water resources crisis.However,the security problems brought by brackish water irrigation have always been the focus and difficulty of research.This paper analyzes the factors affecting the safe irrigation of brackish water,summarizes the previous research results,and summarizes the safe irrigation mode of brackish water from two aspects:irrigation mode and irrigation method.Then,combined water and salt monitoring and numerical model,the paper summarized the research on precise security irrigation based on brackish water quality standards,expounded the farmland regulation measures to solve the problem of soil security under brackish water irrigation and summarized the future research trend of brackish water irrigation safety to promote the brackish water safety efficient utilization and farmland irrigation.
