基于CNKI文献统计的中国再生水灌溉研究分析

Research and analysis of reclaimed water irrigation in China based on CNKI literature statistics

再生水灌溉是缓解农业水资源紧缺的重要举措.本研究以CNKI期刊数据库为数据来源,利用EXCEL和SPSS软件对1991―2021年公开发表的有关再生水灌溉的研究型期刊文献进行了数据梳理与统计,从文献主题、试验因素、研究区域尺度、灌溉年限等方面对近30a的中国再生水灌溉研究进行了定性和定量分析.研究结果表明:再生水灌溉标准有待进一步优化与落实;基于再生水灌溉的安全和效率,应根据风险控制的原则确定灌溉参数和水肥管理制度;再生水在土壤-作物-地下水-空气系统的迁移转化需长期持续监测评估.

Reclaimed water irrigation is an important measure to alleviate the shortage of agricultural water resources. The study analyzed the reclaimed water irrigation research literature data from 1991―2021by EXCEL and SPSS as well as used the research method of literature metrology based on CNKI database as the data source. A qualitative and quantitative analysis of reclaimed water irrigation research in China in the past 30 years from the aspects of the literature topics, experimental factors, research area scale and irrigation years was carried out. The results show that the irrigation standard of reclaimed water needs to be further optimized and implemented. Based on the safety and efficiency of reclaimed water irrigation, irrigation parameters and water and fertilizer management system should be determined according to the principle of risk control, and the migration and transformation of reclaimed water in soil-crop-groundwater-air system needs long-term continuous monitoring and evaluation.
