基于CiteSpace的水稻降镉技术的研究现状和发展趋势预测

Research Status and Development Trend Prediction of Rice Heavy Metal Cadmium Pollution Reduction Technology Based on CiteSpace

摘要: 近年来，随着工业化和城市化进程加快，我国耕地受重金属污染严重，而作为我国重要的粮食作物之一的水稻，对重金属镉的富集能力较强，受污染风险较大，严重威胁我国粮食安全，其治理迫在眉睫。该研究利用CNKI中国知网数据为样本，利用CiteSpace6.1.R6软件对水稻重金属镉污染降镉技术进行了可视化分析，明确了该领域的当前的研究现状以及热点方向和趋势，并为进一步研究提供了参考。

Abstract: In recent years, with the acceleration of industrialization and urbanization, China’s arable land is seriously polluted by heavy metals. As one of the important food crops in China, rice has a strong ability to accumulate heavy metal cadmium, posing a significant risk of pollution, posing a serious threat to Chinese food security, and its governance is imminent. This study used CNKI database as a sample and CiteSpace6.1.R6 software to conduct a visual analysis of the cadmium reduction technology for heavy metal cadmium pollution in rice, clarifying the current research status, hot spots, and trends in this field, and provide references for further studies.
