Comparative Analysis of Current Situation of Watershed Ecological Protection Research between China and Foreign Countries
Abstract
In order to compare the research status in the field of watershed protection between China and foreign countries, this paper uses the Web of Science database and CNKI database as the data source, and citespace analysis tools to display the statistical results of data in the form of knowledge maps from the aspects of the number of papers, keyword co-occurrence, The results show that: ① The research on river basin protection in various countries shows a trend of overall rise and intermittent fluctuation, and China has a feature of high volume of documents and low centrality; ② China's research mainly covers the Yangtze River Economic Belt, ecological compensation, land use, sustainable development, water resources, etc., while foreign research focuses on deforestation, eutrophication, protected areas, land use change, fisheries, etc. This paper summarizes the research hotspots and research methods of watershed protection in China and foreign countries.
