In this paper,the development history of constructed wetlands was summarized,and the current research situation of its greenhouse gas emissions was analyzed.The effects of wetland type,substrate type,influent C/N,plant species and dissolved oxygen concentration on greenhouse gas emissions were described in detail.On this basis,the specific measures and effects of greenhouse gas emission reduction in constructed wetlands were reviewed.Finally,the development direction of greenhouse gas emission reduction in constructed wetlands was prospected.
