基于CiteSpace的土壤法律研究可视化分析

以Web of Science数据库为基础,对1987—2017年的文献进行可视化分析,旨在了解土壤法律研究领域的热点及发展趋势。结果表明:该领域国际上近三十年发文量呈递增趋势,我国在“土十条”颁布后发文量增长显著。发文主要集中在美国、中国、法国等国家,发文机构主要有中国科学院和美国农业部农业研究局。关键词共现图谱显示,土壤、模型、水、重金属、多孔介质、迁移、行为和流动等出现频率较高,归纳来看研究热点主要体现在模型在土壤研究中的应用、污染物的集中研究以及与土壤密切相关的其他领域研究。关键词共现时区分析发现,强度、去除、毒性、微量元素以及风险评价等代表了该领域的前沿研究内容和重要发展趋势。

Visualization analysis of law on soil based on CiteSpace

Based on the database of Web of Science, visualization analysis is conducted on the literature from 1987 to 2017 in order to understand the hot-spots and development trends in the field of legal research on soil. The results show that the amount of papers in this field has been increasing in the recent 30 years, and that of China has increased significantly after Ten Articles on Soil was issued. The published papers are mainly from USA, China and France, etc., and the institutions that produced more papers mainly include Chinese Academy of Sciences and USDA Bureau of Agricultural Research. The keyword co-appearance network shows that soil, model, water, heavy metal, porous media, transport, behavior and flow have had higher frequency. In summary, the research hot-spots mainly include the application of model in soil research, the concentrated study of pollutants and other fields closely related with soil. Time zone analysis of keyword co-appearance shows that strength, removal, toxicity, trace element and risk assessment represent the frontier research contents and important development trends in the field.
