了解不同水体的水质及其影响因素，对于半干旱地区内陆封闭湖泊流域的水资源管理至关重要。但是，一般都是将地下水或地表水分开评价，忽略了不同水体之间的差异。通过分析岱海流域枯水期和丰水期地下水、泉水、河水和湖水沃茨的水化学资料，评价了岱海流域不同水体的水质状况及其影响因素。地下水（81.48%）、泉水（80%）和河水（83.33%）的水化学类型以HCO 3-Ca·Mg为主，湖水以Cl-Na为主（100%）。地下水、泉水和河水适合饮用和农业灌溉，但丰水期地下水水质比枯水期差。Na+和Cl-是影响湖泊水质的主要因素。地下水中NO3-浓度平均值为28.39 mg/L，其非致癌危险系数表明，高风险区主要分布在天城区和麦胡图北方。地下水、泉水和河水的水化学组成主要受岩石（硅酸盐和碳酸盐）风化和阳离子交换的影响，农业活动是地下水NO3-的主要来源。湖泊水化学成分主要受蒸发作用和岩盐溶解作用的影响。因此，应优先考虑地下水NO3污染和湖水盐碱化。这些研究结果提供了一个更深入的了解在半干旱地区封闭的内陆湖泊流域的水质及其影响因素，并可以用于制定生态系统的保护和水资源管理战略在岱海湖流域。
Understanding the water quality and its influencing factors of different water bodies is essential for managing water resources in closed inland lake basins in semi-arid regions. However, generally, groundwater or surface water is assessed separately, and the differences among different water bodies are neglected. This study assessed the water quality and its influencing factors of different water bodies in the Daihai Lake Basin (a closed inland lake basin in a semi-arid region) by analysing the hydrochemical data of groundwater, and spring, river, and lake waters in the dry and wet seasons. The dominant hydrochemical type of groundwater (81.48%), spring water (80%), and river water (83.33%) was HCO3–Ca•Mg, while that of lake water was Cl-Na (100%). Groundwater, spring water, and river water were suitable for drinking and agricultural irrigation; however, the groundwater quality was worse in the wet season than in the dry season. Na+ and Cl– majorly affected the lake water quality. The mean NO3– concentration in groundwater was 28.39 mg/L, and its non-carcinogenic hazard quotient indicated that high risk areas were mainly distributed in Tiancheng and northern Maihutu. The hydrochemical compositions of groundwater, spring water, and river water were mainly influenced by rock (silicate and carbonate) weathering and cation exchange, and agricultural activities were the main sources of groundwater NO3–. Moreover, the lake hydrochemical composition was mainly affected by evaporation and halite dissolution. Thus, groundwater NO3– pollution and lake water salinisation should be prioritised. These findings provide a more thorough understanding of water quality and its influencing factors in the closed inland lake basin in the semi-arid region, and can be used to develop the protection of ecosystems and water resources management strategies in the Daihai Lake Basin.
