基于Web of Science统计的人工湿地处理污水研究态势分析

Trends analysis of wastewater treatment used by constructed wetlands based on Web of Science statistics

基于Web of Science数据库,对国内外近16 a来人工湿地处理污水研究成果的文献进行了统计,以了解人工湿地处理污水学科领域的发展态势。结果表明,2001—2016年,国际相关研究成果的发文量随年份表现为波动变化,总体呈上升趋势。发文量排名前5的国家分别是中国、美国、西班牙、加拿大和德国,中国的贡献最大,占21.1%,2007年之后发文量增加幅度较大。与欧美国家相比,中国的文献引用率较低,高影响因子的文章较少,研究水平和深度还有待进一步提高。文章简要分析了中国人工湿地处理污水的研究现状,并对未来发展作了展望。

Based on database provided by Web of Science,literature of the research results of wastewater treatment that had been used by constructed wetlands in recent 16 years were analyzed both in China and abroad in order to understand the development of wastewater treatment in constructed wetlands. The results showed that the publication quantity of international research findings was fluctuated with years from 2001 to 2016,and in general they were in an uptrend. The top five countries in terms of publication quantities were China,USA,Spain,Canada and Germany,among which China contributed the most,accounting for 21. 1% and showing a great growth in publication quantities after 2007. Compared to western countries,China was low in citing rates of literature and in short of articles with high impact factors,which indicated the level and depth of China research remained to be further improved.This paper briefly analyzed the present research situation of wastewater treatment that had been used by constructed wetlands in China,and looked into the future development with positive anticipation.
