中文摘要:

      目的 对河流污染物通量领域的研究热点进行研究。方法 本文通过以WOS数据库为基础, 运用文献计量学的基本方法, 对1995~2013年间收录的与河流污染物通量主题相关的文献进行了计量分析。结果 河流污染物通量领域是最近发展起来的热门研究领域, 研究重心主要在沉淀、营养、重金属等方面。结论 美国在该领域研究水平处于世界领先, 其次是中国。中国在该领域的研究具有热门但影响不大的特点。另外, 近期的河流污染物通量研究显示出缓慢增加的态势, 需要新的突破来促进其发展。

英文摘要:

      Objective To investigate the research hotspot in the river pollutant flux field. Methods In this paper, literatures about the river pollutants flux between 1995~2013 were studied on the base of WOS database. The research hotpot was analyzed based on bibliometrics. Results The river pollutant flux was the popular research field recently, and its research focus included precipitation, nutrition and heavy metals, etc. Conclusion The research level of the United States is the most advanced, and followed by China. In this area, there are a lot of literature from China, but few of them have profound effect. In addition, the number of literature of river contaminants fluxes increases slowly, so it needs new breakthroughs to promote the development.
