Abstract: In recent years, global warming has aroused great attention, while the thickness of the active layer of permafrost is an indicator for climate change.The impacts of climate change on greenhouse gas emissions in permafrost and its response mechanism have become hot topics in environmental geo-science research.This paper summarized the ways of producing greenhouse gases such as CO₂, CH₄ and N₂O in the frozen soils of the Qinghai-Tibet Plateau, Daxing'an Mountains and Xiaoxing'an Mountains, and discussed the effects of temperature changes, precipitation patterns and nitrogen deposition on greenhouse gas emissions from frozen soils in China.Temperature, precipitation and nitrogen deposition significantly change soil physical and chemical properties and microbial activity, thus affecting soil carbon and nitrogen cycle and resulting in changes in greenhouse gas flux.The response of greenhouse gases to environmental changes in different soil ecosystems is different.Aiming at providing scientific basis for developing policies to adapt to global changes, future research should be highlighted on the response of greenhouse gases in different ecosystems to environmental changes.
