基于文献计量学的我国入海河口营养盐研究状况分析

为了解我国入海河口营养盐研究状况，基于中国知网和Web of Science数据库中1981－2017年我国入海河口营养盐研究期刊论文数据，借助CiteSpace软件文献分析功能，梳理了近40年来我国入海河口营养盐相关研究的发展态势与热点。结果表明:我国入海河口营养盐1981－2017年间的中英文论文发文量增长迅速，英文论文数量在2013年后大幅超过中文，体现了我国入海河口营养盐研究的高热度与国际化；随着时间的变化，我国入海河口营养盐研究的区域、内容和深度不断增加，2000年前主要关注营养盐的含量与分布特征，2000年后的研究内容扩增为营养盐的类型与含量、时空变化与影响因素、环境效应与引发机制、调控与治理等方面。新时期，我国入海河口营养盐研究应加强各类营养盐的形态与转换机制、生物地球化学循环过程与机理、生态环境效应与调控方面的研究；同时，应提升营养盐实时监控技术研究，在流域科学与地球关键带理论下开展入海流域-河口-近海营养盐一体化研究。

Analysis on research status of nutrients in estuary of China based on bibliometrics

In order to study research situation of nutrients in the estuary in our country, based on the data of our country nutrients research in the estuary from 1981 to 2017 in CNKI and WOS database, and with the help of document analysis functions of the CiteSpace software, this article sorts out the development trend and hot spots of the research related to nutrients in the estuary in our country over nearly 40 years. The results indicate that the number of published papers in Chinese and English increased rapidly between 1981 and 2017, and the number of theses in English significantly exceeded that in Chinese after 2013, which embodied the high popularity and internationalization of the nutrients research in the estuary in our country. With the change of time, the region, content and depth of the nutrients research in the estuary in our country continually increase. Before 2000, we mainly paid close attention to the nutrients content and distribution characteristics. After 2000, the research contents were amplified into types of nutrients and contents, temporal and spatial variation and influence factors, environmental effects and solicitation mechanisms, regulation and governance and so forth. In the new period, the study on the form and transformation mechanism, biogeochemical cycling process and mechanism, ecological and environmental effect and regulation aspect of all kinds of nutrients should be strengthened in the nutrients research in the estuary in our country. At the same time, we should promote the research on real time supervise and control technique of nutrients, and carry out the integration research on the sea of drainage basin - river mouth - offshore nutrients under the watershed science and theory of the critical zone of the earth.
