基于知识图谱和PSR框架的北京区域土壤重金属研究现状分析
The current status of the soil heavy metals research in Beijing based on mapping knowledge domain and PSR framework
摘要
Abstract
In order to understand the research status of soil heavy metals in Beijing systematically,the development process and structural relationship of soil heavy metals research in Beijing are visualized with combination of mapping knowledge domain and traditional literature review,based on the Chinese literature on soil heavy metals studies in Beijing.The knowledge was then systematically mined and integrated using the framework of pressure-state-response.The results show that:1) Three stages of the soil heavy metals research in Beijing are conducted,large-scale basic investigation stage (before 1990),small-scale targeted research stage (1991-2000) and the integrated research (after 2001).The major groups including CHEN Tongbin,WANG Jihua,J I Hongbing,and SUN Danfeng,et a/.,provide a large amount of data and theoretical support for Beijing soil heavy metal risk managements2) The accumulation state of soil heavy metal is related with industrial structure and land use,meaning different land use types have different accumulation characteristics.The probability of heavy metal potential risk falls into the safe category for most areas.The government has implemented a series of pollution reduction measures since 1990s leading to reduction in the accumulation rate of soil heavy metals in Beijing.关键词
