嘉陵江生态环境研究回顾与展望——基于文献计量的可视化分析

Review and Prospect of Ecological Environment Research on the Jialing River:Visualized Analysis Based on Bibliometric

嘉陵江是长江举足轻重的一条支流,是沿岸地区融入长江经济带的纽带,也是沿岸城市发展和居民生活必不可少的生态资源。因此,嘉陵江生态环境的研究受到了广大学者的关注。文章检索了中国知网(CNKI)数据库和Web of Science(WOS)核心数据库关于嘉陵江生态环境研究的论文,分别得到了347篇和62篇,利用CiteSpace软件进行可视化分析,从发文量、核心作者、主要机构和关键词等方面进行了探讨。结果表明:随着时间发展,发文量总体呈上升趋势,在2021年达到最高;论文发表的主要机构是西华师范大学、西南大学和重庆大学。CNKI数据库(1979—2021)中显示,研究区域主要分为嘉陵江上游、中游和下游地区,研究主题集中在植被的本底调查、水质条件、评价等方面;WOS数据库最近10年(2011—2021)的论文可分为三大类,第一类是对生物(主要是鱼类)的研究,第二类是对污染的研究,第三类是研究方法;大量生态模型以及3S技术被应用在嘉陵江流域的研究中,研究主题主要是风险评价、污染等方面。同时结合2个数据库的结果发现,学者们都重点关注嘉陵江水质条件和评价等方面,并研究了嘉陵江对三峡库区水环境的影响。在当前国家高度重视生态环境保护及重点关注长江经济带发展的大背景下,文章为未来对于嘉陵江流域的研究提出了一些研究方向。

As an important tributary of the Yangtze River,the Jialing River is the link between the coastal areas and the Yangtze River Economic Belt.It is also an indispensable ecological resource for the development of cities and the life of residents along the river.Therefore,the ecological environment of the Jialing River has attracted the attention of many scholars.In this paper,347 and 62 papers on the ecological environment of the Jialing River are retrieved from the CNKI database and Web of Science(WOS)core database,respectively.CiteSpace software is employed to visually analyze the retrieved documents from the number of papers,core authors,main institutions and keywords.The results are as follows:with the development of time,the overall number of published papers is generally on the rise,reaching the highest in 2021;China West Normal University,Southwest University and Chongqing University are the main institutions where the papers are published;according to the CNKI database(1979—2021),the research areas are mainly divided into the upper,middle and lower reaches of the Jialing River,and the research topics are centered on the local investigation of vegetation,water quality conditions,evaluation and other aspects;in the last 10 years(2011—2021),the papers from WOS database can be divided into three categories:the first is the research on living organisms(mainly fish),the second is the research on pollution,and the third is the research on methodology;a large number of ecological models and 3S technologies have been applied to the research of the Jialing River Basin,and the research topics are mainly concerned about risk assessment and pollution;meanwhile,the results of two databases combined find that these scholars have paid close attention to the water quality conditions and evaluation of the Jialing River,and studied the impact of the Jialing River on the water environment of Three Gorges Reservoir area.Under the background that the country has attached great importance to ecological environmental protection and placed emphasis on the development of the Yangtze River Economic Belt,some research directions are put forward for the future study on the ecological environment of the Jialing River Basin in this paper.
