|Lake science is an interdisciplinary subject to study the relationship between human and nature interaction on ecosystem and environment in lakes and their watersheds. In order to explore the development and research frontiers of lake science in China, this paper analyzes the interannual variation trend of the annual output and impact factors through the statistics of 2555 papers of the Journal of Lake Sciences published in the past 30 years (1989-2018) and the visual knowledge map by CiteSpace V. The results show that the annual volume, citation frequency and impact factors of the Journal of Lake Science display a steady increase trend, and indicate the stable and extensive academic influence of the journal. The relevant research scope mainly involves global climate change, lake ecosystems and community structure, lake eutrophication and other aspects. Meanwhile, the research focuses on the areas of lakes widely distributed and fragile ecosystems. According to the keywords, the research hotspots and trends can be divided into three stages. Analysis of the author's structure shows that universities have overtaken research institutes to become the main parts of journal authors in the past 10 years. The analysis of the key words frequency demonstrates that "Taihu Lake", "sediment" and "eutrophication" have been hot topics in the publication. In the past 10 years, phytoplankton and its community structure, the Three Gorges Reservoir have gradually become hotspots. With the further intersection of lake research and remote sensing technology, statistics and simulation, environmental chemistry and so on, lake research field will become more in-depth and refined. At present, lake research has formed relatively stable research teams in lake hydrology and ecosystem, lake ecological restoration and environmental assessment, sedimentary environment and global change. Universities and research institutes have become the main body of lake research with obvious regional and agglomeration effects. Statistical analysis of the download volume of the journal shows that the journal website has become the main channel for readers to study and download papers. The statistical analysis of CNKI database suggests that the published papers have been cited by different numbers of readers in the past 30 years, with the highest citation frequency of 636 times and 24 citations per article. Analysis of high-cited papers indicate that, as an important carrier of ecological environment protection, strengthening the prevention of lake pollution, prediction of lake eutrophication and ecological restoration technology have become hotspots and trends in related research. At the same time, the research on material exchange, quantitative assessment of human impact, health and management, and protection of lake wetland ecosystem will be further accelerated with the construction of the national lake basin data platform and the integration of big data. The application of lake research results in the region will provide strong support for improving the quality of the water environment, ensuring the safety of regional ecological environment, and improving lake ecological protection and environment.
