    Research Trends of Agricultural Non-Point Source Pollution Risk Assessment Based on Bibliometric Method

    • The purpose of this study was to objectively analyze the research progress, research hotspots and research trends of agricultural non-point source pollution (AGNPSP). The research was based on CNKI database and Web of Science database. Statistical analysis was carried out by bibliometric method from the time of publication, research topics, research areas and research method. And relevant analysis was also carried out in combination with GIS technology. The results show that: (1) The total number of the articles published in the two databases was generally on the rise. As on June 15, 2019, the total number of the articles published in the two databases was 147 and 541, respectively. In the five time periods before 2000, 2001-2005, 2006-2010, 2011-2015 and 2016-2019, the average annual numbers of articles published in CNKI and Web of Science databases were 0, 0.50, 3.80, 13.6, 19.5 and 3.22, 10.2, 21.6, 30.6 and 52.25, respectively. (2) The two databases mainly focused on AGNPSP, risk assessment, output coefficient model, hydrological model and GIS spatial analysis, but there were obvious advantages on international research over China in the field of toxicology research. (3) Hotspot analysis found that there were five agglomeration areas in China: Beijing-Tianjin-Hebei, Northeast three provinces, Yangtze River Delta, Shandong and Chongqing-Guizhou-Sichuan, and four agglomeration areas in the world: China, the United States-Canada, Britain-France-Germany, Brazil. The publication vol-LMumes in the two databases in Anhui Province were the highest with 13 articles and in China with 165 articles, respectively. (4) There were some differences in the methods of risk assessment research at different scales, and the GIS technology could play a better role in different scales. On the basis of literature analysis, the existing problems were analyzed from basic data observation and acquisition, mechanism research, model self-development, standard formulation and so on. And suggestions were put forward to researchers for reference in this field.
