Abstract:

Rice fields are one of the major sources of greenhouse gas (GHG) such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), and the production and emission of GHG in rice fields has always been a hot topic in related research. IPCC predicts that future global climate change is mainly manifested as global warming, increased atmospheric CO2 concentration and near-surface ozone (O3) concentration. The three factors have different effects on GHG emissions in rice fields. Meanwhile, global climate change also affects microbial communities in paddy fields, thus directly or indirectly affecting greenhouse gas emissions. This research reviewed the recent literatures to provide an overview of the following topics: the impact of global climate change on greenhouse gas emissions from rice fields; the impact of global climate change on microbial communities in rice fields; the impact of paddy microorganisms on greenhouse gas emissions in the context of global climate change; and the application of key microorganisms in rice fields to reduce greenhouse gas emissions in recent years. It is pointed out that subsequent studies should comprehensively consider the effects of multi-factor climate change on GHG emissions in rice paddies and strengthen the research on the mechanisms involved.

Key words: global warming, increased atmospheric carbon dioxide concentration, increased near-surface ozone concentration, greenhouse gas, microbial communities, emission reduction, rice fields
