基于 CiteSpace 的极端气候事件生态效应研究进展.

Under the global warming, the research on ecological effects caused by extreme climate events has received widespread attention. Based on a total of 913 literatures collected by the China National Knowledge Infrastructure (CNKI) and the Web of Science Core Collection database from 2000 to 2020, CiteSpace software was applied to visualize and analyze the current research status, progresses and trends of ecological effects caused by extreme climate events. The results showed that the number of publications in this field experienced three phases: slow growth, steady growth, and rapid growth. The number of publications in China was seriously insufficient and relatively scattered compared with that in foreign countries over the same period. The institutions and authors with the highest publications were the Chinese Academy of Sciences and Beierkuhnlein Carl, respectively. Keywords with high frequency of appearance included "climate change", "drought", "response", "temperature", and "extreme climate". Current research on the ecological effects of extreme climate events mainly tends to focus on the impacts of extreme drought, extreme precipitation and extreme temperature on terrestrial ecosystems. The carbon cycle, resistance and stability, sensitivity and dynamic evolution of ecosystems under extreme climate have been research hotspots in recent years. In the future, it is necessary to standardize the terminology related to extreme climate events and to carry out long-term ecological effects research on discrete and compound extreme climate eventsusing new techniques methods.
