英文摘要Our understanding of water-soluble organic constituents and their transformation in the unique aqueous continuum over cryosphere region is scarce. Here, dissolved organic carbon (DOC), dissolved organic nitrogen (DON), and dissolved total nitrogen (DTN) and water-soluble inorganic ions in multiple water bodies from the eastern Tibetan Plateau (TP) cryosphere are systematically determined from a suite of field campaigns, laboratory experiments, linear regression analysis, and multiple comparisons, etc. We found that the water bodies located at high elevation have much lower DOC contents compared to the samples at lower elevation, there has significant altitude dependence of DOC abundance in water bodies over the study area (elevation range: 1971-4700 m asl). Comparison of optical properties, source apportionment, chemical analysis and model simulation of the water bodies provide evidence that the atmospheric deposition of organic species in high mountains is transported to plateau lakes in the northeast of TP via alpine runoff (45%) and snow/ice meltwater (20%). Further, dominance of anthropogenic activities in lower elevations can contribute (35%) to the observed altitudinal dependency. Thus, this preliminary study represents the first systematic investigation of the transport and cycling of organic carbonaceous matter and nitrogenous matter in eastern TP and warrants more robust in-situ observations and measurements in future in High Mountains of Asia.
