Abstract The hydro-chemical characteristics and trophic status of reservoirs are shaped by a combination of natural conditions and anthropogenic effects within the watershed. This study focuses on Xiaowan Reservoir (XW) and Danjiangkou Reservoir (DJK) to analyzes the main ions characteristics and spatial variations of nitrogen (N) and phosphorus (P) nutrients in their water bodies, we identify the primary sources of these ions and interprets the nutrient status of these karst reservoirs, along with the influencing factors. The results show that: The water chemistry of the karst reservoirs is governed by rock weathering, resulting in HCO₃·SO₄-Ca and HCO₃-Ca types for XW and DJK respectively; Both reservoirs exhibit high anthropogenic inputs of SO₄^2-and NO₃^-; In both reservoirs, nitrogen (N) and phosphorus (P) predominant exist in dissolved forms. While no carbon-limitation was observed, N-limitation is evident in XW and P-limitation in DJK, leading to a mesotrophic status in both reservoirs; The stoichiometric ratio of carbon (C), nitrogen (N), and phosphorus (P) are the primary factors influencing the comprehensive trophic level index (TLI) of the reservoirs. This is attributed to the karst hydrochemical background and high weathering rates; Under different N and P limiting conditions, the trophic status is affected by various factors, with the C to P ratio-sensitive to rock weathering, climate change, and anthropogenic inputs-emerging as a key determinant of water quality; To optimize the evaluation indices for assessing the trophic state and managing water quality in karst reservoirs under diverse hydrological conditions and functional roles, it is essential to analyze the effects of water chemical characteristics and stoichiometric ratios of biogenic elements on trophic status based on the analysis of nutrient limitations in water bodies.
