The invention discloses an artificial wetland system for purifying rainwater runoff nutrients. The system comprises a wetland system, which is divided into three separation areas, namely a first separation area, a second separation area and a third separation area, wherein the first separation area and the third separation area adopt surface flow wetlands; the second separation area adopts underground flow wetlands; the first separation area and the second separation area comprise at least two water bodies, and the water bodies are connected through vegetation channels; and the third separation area adopts a whole water body. The surface flow wetland system disclosed by the invention has the characteristics of continuous flow, sufficient oxygen and diversity of aquatic plants, shows a moreeffective ammonia nitrogen attenuation phenomenon by promoting nitrification, and shows an organic matter degradation phenomenon by absorption of aquatic plants and the degradation effect of a biofilm attached to the surface
