我国农田重金属污染生态补偿研究现状与展望——基于CiteSpace知识图谱分析

Current status and prospects of ecological compensation for heavy metal pollution in farmland in China:Based on CiteSpace knowledge mapping

采用文献计量学结合CiteSpace软件,以数据可视化作为主要手段,绘制科学知识图谱,分析并总结了中国2001—2018年间农田重金属污染生态补偿的研究现状。结果发现:1)整体上我国在该领域的研究起步晚,相关研究首次出现在2001年,发文量大致可以分为缓慢增长、下降、迅速增长和波动下降4个阶段,尚未形成核心的研究作者或研究机构;2)研究热点主要围绕生态补偿、重金属污染、污染防治、生态文明等,污染防治在整个共线网络中起到了基础性的作用,热点关键词首次出现时间多集中在2013-2017年;3)研究主题具有多元化的特点,主要包括"重金属污染"、"法律制度研究"、"补偿机制研究"3个研究主题;4)未来农田重金属污染生态补偿政策、方法与实践路径研究仍需进一步探索与完善。

Based on CiteSpace,this study uses data visualization as the main means to draw scientific knowledge maps,analyzes and summarizes the research status and development trend of ecological compensation for heavy metal pollution in farmland in China from 2001 to 2018.The results show that:1)On the whole,China’s research in this field starts relatively late.The related research first appears on 2001.The number of publications can be roughly divided into four stages,which are slow growth,decrease,rapid growth and fluctuation decline.Core researchers and institutions have not yet formed.2)The research hotspots mainly focus on topics such as ecological compensation,heavy metal pollution,pollution prevention and ecological civilization.Pollution prevention plays a fundamental role in the whole research.The hotspot keywords first appeared are mainly on 2013-2017.3)The research themes display diversified characteristics,including three research themes of"Heavy metal pollution","Legal system research"and"Compensation mechanism research".4)In the future,the combination of national policies,the research on the theory,methods and practice path of agricultural heavy metal pollution ecological compensation still need further exploration and development.
