摘要
分析了劣质水资源化利用在缓解用水压力、优化水资源配置、产生特有灌溉效益等方面的重要意义,简要概括了劣质水灌溉的研究与实践进展,重点阐述了对土壤、作物、地下水的影响。今后应着重开展农田污染物迁移与劣质水处理、劣质水灌溉技术与标准以及劣质水灌溉的环境影响与生态风险等研究。
The significance of the utilization of poor-quality water to alleviate water shortages , the optimization of water resources allocation , and the production of specific irrigation benefits are analyzed in this paper .Advances in the study and practice of poor-quality water irrigation are summarized in brief .The impacts of poor-quality water irrigation on soil, crops, and groundwater are analyzed in detail .It is suggested that future research should be focused on contaminant migration and poor-quality water treatment in croplands , poor-quality water irrigation technologies and standards , and environmental impacts and ecological risks of poor-quality water irrigation .
