The paper identifies a gap in understanding the coupling relationship between dynamic environmental factors and GHG emissions under alternate wetting and drying irrigation methods. The study aims to fill this gap by investigating methane, carbon dioxide, and nitrous oxide emissions from intermittently irrigated coastal rice fields in northern Zhejiang, China.
