基于文献计量的国内土壤重金属污染研究

Research on Soil Heavy Metal Pollution in China Based on Bibliometric Analysis

选取中国知网作为数据来源,就国内土壤重金属污染研究进行了文献计量探讨。结果表明:文献数量多年呈波动上升趋势;研究成果大多以期刊论文的形式体现;研究人员之间相对独立;研究区域在华北、东北、西北和东南沿海均有分布;研究方法总体朝定量方向前进;研究内容侧重于土壤重金属污染的治理。

Bibliometric analysis was carried out on the research of soil heavy metal pollution in China by selecting CNKI as a data source. The results showed that the number of literature had been fluctuating increasing for many years;research achievements were embodied in the form of periodical articles;researchers were relatively independent;the areas where the research were carried out distributed in the northern China, northeast, northwest, and southeast coasts of China;the quantitative research method was used more and more in the whole;the contents of the research focused on the treatment of soil heavy metal pollution.
