湖泊氮沉积研究热点与发展趋势
Research Hotspot and Development Trend of Lake Nitrogen Deposition
摘要
Abstract
To analyze the research development stage,hotspots,and future trend of lake nitrogen deposition worldwide from 2000 to 2022,the bibliometrics software CiteSpace was applied to visualize the related literatures in the Web of Science(WOS)and China National Knowledge Infrastructure(CNKI),focusing on collaborative networks,literature citations,and keywords.Results show that:(1)In the past 23 years,the research achievements in lake nitrogen deposition have been concentrated in China and America.(2)The hotspots include eutrophication,nitrogen morphology and its transformation from watershed perspective,and lake comprehensive environmental effects in turn.(3)Future research needs to focus on the dynamic change of nitrogen and its drivering factors in watersheds under the dual effects of climate change and human activities,as well as the improvement of lake nitrogen databases and the assessment of compound pollution.关键词
