中文摘要：

再生水灌溉是解决水资源短缺的有效途径之一。综述了国内外再生水灌溉的研究现状，并对再生水灌溉的前景及今后的研究重点进行了分析。再生水灌溉对地下水的影响主要集中在地下水的盐化、氮磷化合物及其迁移转化方面；再生水灌溉对土壤的影响主要集中在土壤盐分和重金属的累积、对土壤微生物的影响等方面；再生水灌溉对作物的影响主要集中在作物的品质、产量；再生水的安全灌溉技术、不同灌溉技术对土壤化学性质、作物产量、卫生方面的影响；再生水灌溉制度的研究。今后研究重点应集中在以下方面：再生水灌溉标准的制定，氮、磷、有机物、重金属在土壤植被系统中的迁移转化规律，再生水安全高效灌溉技术，研究建立再生水灌溉环境影响和健康风险评价指标与评价方法。

英文摘要：

Reclaimed water irrigation is one of the effective measures to deal with the scarcity of water resources. The actuality of research on reclaimed water irrigation at home and abroad is summarized and the prospect of reclaimed water irrigation and the key points of future research are analyzed. The research on effect of reclaimed water irrigation on groundwater focused on salting, the composition of phosphorus and nitrogen and its transfer. The research on soil focused on the accumulation of salinity and heavy metal and the influence on soil microorganism, etc. The research on crop focused on the quality and output. Safe irrigation technologies, the effect of different irrigation technologies on soil chemical properties, crop yield, and sanitation are analyzed, too. Also, there are some reports about reclaimed water irrigation system. The future research should concentrate on the below aspects, including reclaimed water irrigation standards, the transfer and migration rule of phosphorus, nitrogen, organism and heavy metal, safe irrigation technologies, the establishment of environment effect and healthy risk evaluation index and method.
