基于Web of Science数据库的土壤污染修复领域发展态势分析

土壤污染修复是当今农业、生态和环境科学领域的研究热点。为明确该领域在世界范围的研究布局,基于Web of Science平台科学引文索引扩展版(Science Citation Index Expanded,SCIE)数据库对2005—2013年土壤污染修复领域的SCI论文进行计量学统计,探讨该领域的研究现状、研究重点及发展趋势。结果显示,在世界范围内土壤污染修复领域的发文量逐年稳步增长,其中以中国、美国和印度发文量较多,技术成熟度和重视程度也较强。美国、中国、英国和印度的论文质量和影响力较高,表征发展中国家中国和印度在土壤污染修复领域的研究实力也跻身世界前列,是土壤污染修复领域重要的参与者和引领者。中国科学院、浙江大学和西班牙高等科学研究委员会是其主要发文机构,中国国家自然科学院基金、973国家重点基础研究发展计划、欧盟、美国能源部、863国家高技术研究发展计划是其主要的项目资金来源。土壤污染修复研究涉及的学科领域分布广泛,其中以环境科学与生态学领域发文量最多,并向其他学科渗透,交叉研究将会更为普遍。今后土壤污染修复技术发展也将继续呈现多样化、友好化和高效化,更加注重土壤污染修复效果评价和经济效益评估。该研究结果可为土壤环境学科的发展、研究布局的规划以及我国土壤污染修复技术的创新提供思考与借鉴。

Trends in research on contaminated soil remediation based on web of science database

Remediation of contaminated soil is a hot research topic in the field of agricultural, ecological and environmental sciences. In order to understand the current status of world-wide research on contaminated soil remediation, research literature during the period of 2005~2013 was retrieved from the Science Citation Index Expanded(SCIE) database and analyzed using bibliometrics. Results showed that the quantity of publications in the field of contaminated soil remediation increased steadily year by year. China, United States and India were the top three countries in the number of publications, and showed better performance in technical maturity and research emphasis. The quality and the impact of publications from the United States, China, Britain and India were higher than those from other countries, indicating that the developing countries, such as China and India, have enhanced research capacities in the field of contaminated soil remediation. The Chinese Academy of Sciences, Zhejiang University, and Spanish National Research Council were the major paper-publishing institutions. The National Natural Science Foundation of China, National Basic Research Program of China(973), European Union, U.S. Department of Energy, and National High Technology Research and Development Program of China(863) were the main funding sources. The scientific research activities spanned across a wide range of disciplines, with the most publications appeared in the environmental science and ecology. The interdisciplinary research became a trend. Remediation technologies of contaminated soils would be diverse, user-friendly and highly efficient in the future. More attention should be also paid to evaluation of performance efficiency and economic benefits of remediation techniques. These results provide important insights to the development of soil science and research planning for contaminated soil remediation in our country.
