Understanding the transformation of river dissolved organic matter (DOM) is important for assessing emissions greenhouse gases (GHGs) in inland waters. However, relationships between variations DOM components and GHGs remain largely unknown. Here, parallel factor analysis (PARAFAC) was applied to investigate 46 rivers China. We found that GHG peri-urban were 1.10–2.15 times greater than those urban rivers. Microbial environmental factors (e.g., living cell numbers, microbial activity pH) explained more 70% total variance different ware revealed based on compositional data principal component (CoDA-PCA). Microbial-mediated production degradation quantified, levels 11.8–25.2% Differences carbon emission potential related variances transformations affected by water chemistry NH4–N As). This study clarifies regulatory effects composition emissions, enhances understanding biogeochemical cycle.

Dissolved organic matter (DOM) plays a significant role in the biogeochemical cycle of crucial elements aquatic ecosystem. However, it is still not clear on spectral characteristics water DOM different types alpine wetlands, which have less anthropogenic influences and intensive ultraviolet radiation. Here, we collected 107 samples from marsh, lake, river wetlands Zoige plateau, China, analyzed chemical characteristics, compositions, potential sources chromophoric by combining UV–vis spectroscopy excitation–emission matrix fluorescence coupled with parallel factor analysis (EEMs-PARAFAC). UVC UVA fulvic-like substances were prevailing components DOM, accounted for 23.74–71.59% 16.76–30.01% total intensity, respectively. Compared lake fluoresce intensities higher marsh wetland. Marsh possessed highest SUVA254, E2/E3, E2/E4, E4/E6 suggesting humification degree, relative molecular nominal size, aromaticity. And E2/E4 ratios most than 12, indicating was mainly derived autochthonous wetlands. Wetland strongly affected plateau. These findings may be beneficial sustainable management
