摘要
为揭示当前国内外小流域的研究现状及研究热点,以Web of Science和中国知网(CNKI)数据库作为中英文文献来源,基于文献计量学分析方法定量分析了1998~2018年期间国内外有关小流域研究的相关文献。分析结果表明:(1)国外从2012年开始进入小流域研究的爆发期,国内发文量保持稳定,总体来说小流域研究在国内外逐渐受到重视。(2)通过统计国内外高频关键词,发现国外对小流域的研究更侧重于探究气候变化对小流域的影响,而国内的关注点更多地放在了对小流域水土流失的综合治理。(3)根据国外高频关键词共现网络可视图可以看出,国外关于小流域的研究方向更多样化。(4)从高频关键词聚类分析结果来看,国外更侧重于小流域的水质及气候变化对小流域生态系统的影响等理论研究,国内比较关注小流域生态综合治理和工程建设等应用性研究。总结得出,国内外对小流域的研究方向存在差异,国内在防治小流域水土流失的同时还应借鉴国外研究,找出小流域生态环境被破坏的原因,帮助小流域生态系统恢复。
To elucidate the current research status and hot topics of small catchment at home and abroad,a bibliometrics analysis was carried out to quantitatively analyze literatures about small catchment from Web of Science and China National Knowledge Infrastructure(CNKI)database from 1998 to 2018.The results show that:(1) Foreign small catchment research entered outbreak period since 2012,and domestic publications of small catchment remained stable.In general,the research on small catchment had received increasing attention at home and abroad.(2) By counting the high-frequency keywords,it was found that more foreign researches focused on exploring impact of climate change on small catchments,while domestic researches focused on comprehensive management of soil erosion in small catchments.(3) According to the foreign high-frequency keyword co-occurrence network,it showed that the research directions of small catchments were more diversified.(4)From the results of high-frequency keyword clustering analysis,foreign researches focusd on theoretical research on water quality of small catchments and effect of climate change on small catchment ecosystems.In China,researchers paied more attention on ecological comprehensive management and engineering construction in small catchments.It is concluded that there are differences in the research direction of small catchments at home and abroad,and it is necessary to learn from foreign studies to find out the actual causes of ecological environment destruction while preventing and controlling soil erosion in small domestic catchments,so as to help the ecosystem recovery.
