Abstract: Aims and Methods Global change already poses a serious threat to different freshwater ecosystems by raising water temperatures, changing precipitation patterns and water flow conditions, promoting species invasion, and increasing extreme events. In order to figure out the core contents and highlights of freshwater ecology research in the context of global changes, subject term searching and bibliometric analysis of relevant papers published in the past decades (1900-2018) was done within the scope of web of Sciences. Important findings In this review, the core research contents of freshwater ecology in the context of global change are summarized as :(1) the effects of various elements of global change on individuals, populations, communities and ecosystems; (2) the change of biogeochemical cycle of ecosystem in the process of global change; (3) adaptation strategies of freshwater ecosystems to global changes. In the past 10-15 years, this field has developed rapidly and made breakthroughs as follows: (1) to elucidate the response process and mechanism of freshwater ecosystem structure and function to global climate change, especially water temperature rise; (2) to reveal that freshwater ecosystems (wetlands, lakes, rivers, etc.) are important parts of the global carbon cycle, in which organic carbon burial decreasing and mineralization rate increasing under the influence of global changing drivers. In the future research, it is necessary to strengthen the systematic observation and integration of the total elements of freshwater ecosystem, to research on carbon transport and transformation process base on the river-connected multi-systems, to strengthen basic theoretical research to reveal the adaptation mechanism of freshwater ecosystem to global change.
