摘要

摘要研究了2016-2020年特列茨科湖（阿尔泰东北部）支流水中主要离子（\({text{HCO}}_{3}^{ - }\), Cl-, \({\text{SO}}_{4}^{{2 - }}\), Ca2+, Mg2+, Na+和K+）的浓度。发现了湖泊支流水体离子组成的季节性变化，并确定了这种组成与支流流域生物地球化学条件之间的关系。东部支流和西部支流的排水岸具有不同的地质和地貌结构，其水体中主要离子的浓度和比例也各不相同。研究表明，所考察的大部分支流属于同一水文地质化学面，水体类型为碳酸氢盐-镁-钙型。对三条湖泊支流的离子径流特征进行了计算，并对其流域的化学侵蚀作用进行了评估。

Long-Term Dynamics of Major Ion Concentrations in the Water of Lake Teletskoe Tributaries in the Context of Biogeochemical Conditions in Their Drainage Basins

Abstract

The concentration of major ions (\({\text{HCO}}_{3}^{ - }\), Cl^–, \({\text{SO}}_{4}^{{2 - }}\), Ca²⁺, Mg²⁺, Na⁺, and K⁺) in the water of tributaries of Lake Teletskoe (Northeastern Altai) was studied in 2016–2020. Seasonal variations were found in the ion composition of the water of lake tributaries and a relationship between this composition and the biogeochemical conditions in their drainage basins was established. The waters of eastern and western tributaries, which drain shores with different geological and landscape structure, differ in both the concentrations and proportions of the major ions. It is shown that most of the examined tributaries belong to the same hydrogeochemical facies and carry water of bicarbonate-magnesium-calcium type. Characteristics of ion runoff of three lake tributaries were calculated; chemical denudation in their drainage basins was evaluated.
