Hydrochemical variations of springs in Huanglong Scenic of Sichuan Provience during July

摘要

Methods of automatic hydrochemical logging and in situ titrating combined with indoor analysis were used to study the dynamic variation of the physical chemistry in Huanglong Scenic. The water quantity, pH, conductivity, DO, temperature, bacterial quantity (CFU/mL) of different springs were analysis. It was found that the spring 2#, 5# and 6# were the major source of spring water in Huanglong scenic and the water flow of decreased spring was changed with the change of the rise spring in the same time. HCO_3~- concentration of the rising spring water was around 900ppm, while that of the decreasing spring water approximately 350ppm.
