摘要
再生水灌溉是解决农业用水短缺的有效方式之一.总结了目前国内外学者关于再生水灌溉对土壤质量影响的研究进展,指出再生水灌溉使土壤微生物数量增加;再生水灌溉土壤存在盐碱化的风险;短期再生水灌溉对土壤重金属含量的影响较小.但目前对再生水灌溉对土壤盐分、重金属、N、P等元素以及有机物污染的迁移规律研究较少.在今后的研究中,应侧重于利用模型模拟再生水灌溉条件下主要污染物的迁移规律,评估再生水灌溉对土壤环境影响的风险,建立合理的灌溉制度,为再生水灌溉提供可行性和安全性.
Abstract
Reclaimed water irrigation is one of the effective measures to deal with the lack of irrigation water resources .The research progress on the impact of reclaimed water irrigation on soil quality was summarized by domestic and foreign scholars .The results showed that the soil ir-rigated with reclaimed water increased the amount of soil microbes,and had salinization harmfulness;the heavy metal concentration in the soil irrigated with short-term reclaimed water had little negative effect on the soil.But there was little research on the transfer and migration rule of soil salinity,heavy metal,phosphorus , nitrogen and organism in reclaimed water irrigation at present.The future research should concentrate on using model to simulate the migration of major pollutants under the condition of reclaimed water,assessing the potential risks,establishing a rea-sonable irrigation system,providing the feasibility and safety of reclaimed water irrigation.
