Hydrochemical Variations of Springs in Huanglong Scenic of Sichuan Provience during July

Researchers identified Springs 2#, 5#, and 6# as the primary sources of water in Huanglong Scenic Area, with their flow dynamics closely linked to seasonal variations. Notably, rising springs exhibited significantly higher bicarbonate (HCO3-) concentrations (~900 ppm) compared to decreasing springs (~350 ppm), suggesting distinct hydrochemical processes at play. The study employed a combination of automatic hydrochemical logging, in situ titrating, and indoor analysis to track real-time changes in water quantity, pH, conductivity, dissolved oxygen (DO), temperature, and bacterial levels across the springs. This approach revealed intricate relationships between spring behavior and environmental factors, offering critical insights for understanding the hydrochemistry of this UNESCO World Heritage Site.
