Dissolved organic matter (DOM) is an important component of the biogeochemistry and ecosystem function streams rivers. Unlike inorganic nitrogen nutrients, (DON) nutrients can vary considerably depending on contributions various sources. The properties DOM in natural waters have been measured using fluorescence spectroscopy, which inexpensive compared to more sophisticated chemical analysis fast enough enable its use routine water quality monitoring. However, estimating sources surface from data a similarly efficient manner remains area active research. In this study, we develop simple linear regression method for relative amounts stream or river sample. estimates are accurate than those previous approaches orders magnitude faster compute. Codes implement provided variety computing environments facilitate research applications.

Abstract. Mountainous rivers are critical in transporting dissolved organic carbon (DOC) from terrestrial environments to downstream ecosystems. However, how geomorphologic factors and anthropogenic impacts control the composition export of DOC mountainous remains largely unclear. Here, we explore dynamics three subtropical catchments (i.e., Yinjiang, Shiqian, Yuqing catchments) southwest China, which heavily influenced by activities. Water chemistry, stable radioactive isotopes (δ13CDOC Δ14CDOC), optical properties (UV absorbance fluorescence spectra) were employed assess biogeochemical processes controlling on riverine DOC. The radiocarbon ages Yinjiang River varied widely 928 years BP present. Stepwise multiple regression analyses partial least square path models revealed that geomorphology activities major drivers concentrations DOM characteristics. Catchments with higher catchment slope gradients characterized lower concentrations, enriched δ13CDOC Δ14CDOC, more aromatic matter (DOM), opposite gentle slopes. Variabilities also regulated land use, urban agricultural areas. Furthermore, a proportion uses was less aromatic, recently produced, exhibited degree humification autochthonous humic-like DOM. This research highlights significance incorporating controls sources into understanding quality rivers, globally abundant.
