中文摘要	采用水化学与氢氧稳定同位素技术,通过现场测试和室内分析,对乌尔逊河流域不同类型水体的水化学和氢氧同位素特征进行分析,探讨了水化学和氢氧同位素在水文过程的指示作用。结果表明:流域内河水的水化学类型以Na·Ca-HCO_3型为主,地下水以Na-HCO_3、Na-HCO_3·Cl为主。流域内河水的水岩相互作用要强于地下水,主要离子来源于硅酸岩、石膏及白云岩的溶解沉淀;岩盐、钠、钾长石的风化溶解及部分人类活动的影响。离子受蒸发富集及岩石风化作用较明显,氢氧同位素研究指示出流域内河水与地下水的主要补给源之一均为大气降水,且研究区内的地表水受蒸发作用强于地下水。对研究区地下水及河水 deltaD、delta~(18)O、溶解性总固体TDS(Total Dissolved Solids)及Cl-含量的沿程变化进行分析后明确地下水受径流、左侧基岩裂隙水及孔隙水的共同补给,且地下水也是乌尔逊河的主要补给来源之一,其对乌尔逊河上、中、下游补给比例分别是59.35%、55.90%和52.00%。
英文摘要	In this paper, water chemistry, and hydrogen and oxygen stable isotope techniques are used to analyze the water chemistry, as well as hydrogen and oxygen isotope characteristics of different types of water bodies in the Wuerxun River Basin through on-site testing and indoor analysis. Indicators of water chemistry, and hydrogen and oxygen isotopes in hydrological processes are discussed in this paper. Results showed that the water chemistry and type of surface water within the basin is dominated by Na·Ca-HCO_3 type; groundwater is dominated by Na-HCO_3 and Na-HCO_3·Cl. The water-rock interaction of river water in the basin is stronger than in groundwater, and the main ions in the Wuerxun River Basin come from the dissolution and precipitation of silicate rock, gypsum, and dolomite. These weathering and dissolution processes take place because of the presence of rock salt, sodium, and potassium feldspar, and the impact of some human activities. It was found that various ions are significantly affected by evaporation and weathering of rocks. Hydrogen and oxygen isotopes indicate that atmospheric precipitation is one of the main sources of river water and groundwater supply in the basin. The river in the study area is more strongly affected by evaporation than groundwater is. In order to fully understand the recharge relationship between river and groundwater in the Wuerxun River Basin, the variation of deltaD, delta~(18)O, TDS, and Cl- content was analyzed within the groundwater and river. The analysis showed that groundwater is recharged by runoff, fissure water from the bedrock on the left, and pore water. At the same time, groundwater is also the main source of recharge for the Wuerxun River Basin. The replenishment ratios at the upper, middle, and lower reaches are 59.35%, 55.90%, and 52.00% respectively.
