Comparative Analysis of Mapping Knowledge Domains of Haze Researches between China and Foreign Countries from 1992 to 2016
The journal articles titled with haze in Chinese and English were collected from China Academic Journals Full text Database (CNKI) and Web of ScienceTM Core Collection of Science Citation Index Expanded Database (WOS) during the period of 1992-2016.The knowledge maps of haze research were drawn and analyzed based on bibliometric method.Our findings showed that:(1) the scientific outcomes of haze are increasing with a good developmental trend.USA and China are the leading countries in this field,and National Aeronautics and Space Agency and Chinese Academy of Science are the dominant institutions.(2) There are some differences in haze-topic research hotspots from China and foreign countries.Internationally,the primary research hotspots were accumulation of PM2.5,visibility and aerosol,the secondary research hotspots were photochemical property of haze particles in the Titan's atmosphere.The primary domestic research hotspots were atmospheric pollutants emission and prevention,the secondary research hotspots were respiratory system disease prevention and research & development of air purifier.(3) The collaboration strength,continuity,systematicness and interdisciplinary of haze-topic publications in foreign countries are all significantly superior to those of China.(4) The implications for the future researches of haze field need to intensify photochemical effects,long-term and located observations,coupled with climate and air quality models,and forecast and early warning for haze particle and weather.
