The nitrogen cycle is the key to healthy operation of river ecosystems and plays an important role in maintaining ecological balance, purifying water quality, promoting circulation material. Xisha River was chosen as research object analyze quality condition from 2021 2023, microbial diversity metabolism, functional genes, metabolic pathways body were analyzed using macro-genomics technology. results showed that total (TN) main exceedance factor body, ammonia (NH3-N), TN, phosphorus (TP) factors affecting quality. downstream station (W2) exhibited most significant changes, while upstream (W5) highest biodiversity abundance. top five genera abundance unclassified__c__Actinomycetia, unclassified__p__Bacteroidota, Paenisporosarcina, Candidatus_Planktophila, unclassified__c__Betaproteobacteria. abundant metabolism genes K01915 (nitrate reductase), K00265 (nitrite K01673 (ammonium transporter), K00266 K02575 each contributing critical cycling processes such denitrification, nitrification, assimilation. six major denitrification (M00529), anisotropic nitrate reduction (M00528), (M00529).
