| 利用中国知网期刊全文数据库（CNKI）和Web of Science核心合集英文数据库（WOS），通过对2000—2018年小麦、玉米重金属污染农田修复领域的相关文献进行计量分析并统计归类，了解国内外有关小麦、玉米重金属污染农田土壤修复治理领域的研究趋势及特点，深入分析田间试验条件下不同修复治理技术对小麦、玉米籽粒的降镉效果，为进一步的深入研究与应用提供依据。结果表明，国内外该领域研究起步发展较缓，在2010年之后增速加大，但关注度明显低于稻田；从重金属种类来看，对重金属镉污染的研究热度居首位；在小麦、玉米重金属污染农田修复领域占据重要影响地位的主要发文期刊包括：Journal of Hazardous Materials、Science of the Total Environment、Chemosphere、《农业环境科学学报》以及《生态环境学报》；施用钝化剂/改良剂在该研究领域的受关注度最高；从田间条件下修复效果来看，低积累镉品种的应用籽粒降镉效果最佳，降镉率达57.73%，其次是无机+有机复合类钝化材料。无机+有机复合修复材料和低积累品种应用是小麦、玉米重金属污染农田土壤修复利用的有效技术和研究发展方向。 |
| 英文摘要: |
| The China National Knowledge Infrastructure(CNKI), namely the China Academic Journals Full-text Database, and Web of Science Core Collection Database were used for bibliometrics analysis and statistical classification of relevant literatures on wheat and maize heavy metal-contaminated farmland remediation from 2000 to 2018. The aim was to clearly understand the domestic and foreign research trends and characteristics in this field, and provide a basis for future in-depth research and wider application of different types and effects of remediation technologies under field test conditions. The results showed that local and foreign research development in this field was slow, and although the growth rate had increased since 2010, the degree of concern was significantly lower than that for rice fields. From the perspective of heavy metal types, cadmium pollution was the most studied. The main publication journals in the field of heavy metal pollution restoration of wheat and maize farmland included Journal of Hazardous Materials, Science of the Total Environment, Chemosphere, Journal of Agro-Environmental Science, and Journal of Eco-Environment. Research on application of passivating agent/improver had attracted the most attention. Evaluation of the restoration effect under field conditions indicated that the selection and application of low-cadmium accumulation varieties had the best cadmium reduction effect, with a reduction rate of 57.73%, followed by organic-inorganic composite and inorganic composite repair technologies. Organic-inorganic composite remediation materials and lowaccumulation varieties were both effective technologies and research development directions for the remediation and utilization of wheat and maize heavy metal-contaminated farmland. |
