Water Chemical Characteristics and Irrigation Suitability of Surface Water in Areas Around Yuelu Mountain in Xiangjiang River Basin
Journal Title: Bulletin of Soil and Water Conservation - Year 2023, Vol 43, Issue 4
Abstract
[Objective] The water chemical characteristics and irrigation suitability evaluation of surface water body in areas around Yuelu Mountain in Xiangjiang River basin were analyzed in order to provide theoretical support for ecological environment protection and scientific decision-making of integrated water resources management in this area. [Methods] The study was conducted in the area around Yuelu Mountain. Water samples of precipitation, mountainous creek water, and Xiangjiang River water were collected from December 2020 to November 2021. The water chemical characteristics and factors influencing each water body were analyzed by using Piper diagram, Gibbs diagram, end-member diagram, etc. [Results] The main anions and cations of precipitation were Ca2+, K+, , and , with no obvious water chemical type. The main anions and cations of mountainous creek water were Ca2+ and , and the water chemical types were Cl-Ca·Mg and Cl-Ca. The main anions and cations of Xiangjiang River water were Ca2+ and , and the water chemical type was HCO3-Ca. Mountainous creek water was primarily influenced by atmospheric precipitation and carbonate rock weathering, whereas Xiangjiang River water was more influenced by carbonate rock weathering. [Conclusion] Na+%, SAR, and RSC indexes, and the USSL diagram and Wilcox diagram results were good. The mountainous creek water and Xiangjiang River water in the areas around Yuelu Mountain are suitable for irrigation and are not prone to salt or alkali damage.
