Anaerobic ammonium oxidation coupled to iron (Ⅲ) reduction (termed Feammox) is a recently discovered pathway of nitrogen cycling. However, little known about the pathways N transformation via Feammox process in riparian zones. In this study, evidence zone soil layers (0-20 cm) was demonstrated using isotope tracing technique and high-throughput sequencing technology. The results showed that occurred zones four different (A:0-5 cm, B:5-10 C:10-15 D:15-20 rates ranged from 0.25 mg·(kg·d)-1 0.29 mg·(kg·d)-1. B sample, rate significantly higher than other samples (P<0.05). addition, reducing bacteria played an essential role process, Anaeromyxobacter Geobacter were detected all samples. abundance Overall, co-occurrence suggest can play removal
