非常规水资源农业利用现状及研究进展

由于缺乏合理的水资源管理措施和适当的水处理技术导致淡水资源枯竭和水质恶化问题日益严重,促使再生水、微咸水和雨水等非常规水作为一种新的水资源开发利用方式得到发展,为农业灌溉提供了可靠且稳定的补充水源。然而,非常规水独特的水质特性决定了其农业利用过程中必然会对环境和健康产生众多负面影响,这也成为人们关注的焦点。本文概述了国内外非常规水资源在农业中的利用与研究现状,总结了非常规水资源农业回用的生态风险和相关标准规范,并对非常规水资源农业利用的安全性和可持续性提出相关建议。

The Use of Brackish and Reclaimed Waste Water in Agriculture:A Review

Due to poor water resources management and appropriate water treatment technologies, freshwater resources depletion and water quality deterioration has made reclaimed waste water, brackish water and rainwater,called unconventional water, an important complementary resource for irrigation. However, due to its unique chemical quality, irrigating with unconventional water might lead to some detrimental impact on environment and impose health risks, which has attracted increased attention in both scientific and public community. This paper reviews the current situation of the usage of unconventional water resources for irrigation in both China and beyond, and summarized the potentially ecological risks of unconventional water, as well the national standards for regulating unconventional water irrigation. We also put forwards suggestions to improve safe and sustainable use of unconventional water resources for irrigation.
